Printed with inks that change color in the sun. Unusual colors. The principle of operation of unique car enamels

Photochromic paints

Probably the most popular of special paints. Under influence ultraviolet light change color to the opposite. The change occurs instantly, after turning off the UV light source, the image returns to its original color or becomes colorless.

Photochromic paints are of the following types: colorless/colored and colored/colored.

Photochromic colors under normal lighting.

Photochromic paints in direct sunlight.

Thermochromic paints

Thermochromic paints are activated by heat. If you rub the product printed with such inks, hold it in your hands or expose it to different temperatures, the ink changes color or ceases to be colorless, and then quickly returns to its original state.
Like photochromic, thermochromic inks come in colorless/colored and colored/colored. The temperature at which the change occurs can be determined in advance - for example, the color appears at 22°C and disappears at 32°C.

hydrochromic paints

These colors are activated by water, not by light or heat. White hydrochromic paint is identical in appearance to regular white paint. But when water gets on it, it becomes transparent, and the image under it appears. As the water dries, the image loses transparency again.

UV fluorescent paints

These colors are invisible under normal light, but under the influence of UV-colors begin to glow. There are two types of such inks: one wavelength (360mm) and two wavelengths, which acquire one color under short wavelength UV light (250mm) and another color under long wavelength (360mm). Yellow, green, blue, orange and red UV fluorescent inks are commonly supplied. Most often they are used in the printing of banknotes and other security products.

Optical change inks

When viewed from different angles, these colors significantly change the shade, they reflect various lengths waves of white light in different ways, depending on the angle of incidence on the surface and with the naked eye, this effect can be observed in the form of a change in color from the viewing angle. Usually used when printing passports and driver's licenses.

"Dirty" paints

The peculiarity of these paints is to leave traces when in contact with water, even with wet fingers.

Iridescent paints

Semi-transparent colors with a pearlescent effect. When viewed from different angles, they change shade, shimmering with all the colors of the rainbow. Available in blue, red, green, gold and silver iridescent colors.

Metameric pairs

A metameric pair is two paints that match in hue in one light and differ significantly in another.

The two green squares are, in fact, exactly the same.

"Inflated" paints

As the name suggests, these inks swell and become embossed when heated. This effect is also called "thermal lifting". This paint is used as a protection for products and surfaces made of wood, concrete and metal. During heating, in the event of a fire, the paint swells and its layer increases tenfold, thus forming an effective insulating layer around the surface to be protected.

Glow in the dark (luminescent) paints

If such paint is exposed to bright light and then transferred to a dark room, it will emit a bright greenish light.

Fluorescent paint is different special properties, which give a glow in low light and at night. For some time, she accumulates light and then gives it away for 8-12 hours. This allows you to create various effects on the treated surface. Get original lighting effects or images. So you can create a single light accent or an entire composition.

Luminous paint retains brightness on the applied surface after the lights are turned off or after dark. This ability gets any object in the interior, if applied to it special composition. In stores, such paint is often called fluorescent, phosphor or fluorescent.

Fluorescent paints accumulate light from external sources throughout the day, and with the onset of darkness, they begin to radiate it. In this case, the cycle of action can continue for for long years. All this thanks to a pigment called phosphor. It is a physically stable powder with stable chemical functionality.

The term of use of the phosphor exceeds 30 years. It can be used both for work in the interior and for finishing the facade.

Luminous paint is obtained by mixing with a transparent varnish. It is he who affects the spectrum of use of enamel. It applies to the following:

decorative walls and floors in cafes, restaurants and nightclubs;
phosphor paint is used for interior items such as sofas, tables and chairs;
luminescent details in elements of theatrical costumes and make-up;
alive and artificial compositions from flowers;
on clothes and accessories as logos;
for coloring window frames and gazebos, as well as for other wooden structures;
as tuning cars and bicycles;
on clothes of special services and road signs.

Recently, luminous paint has been used for decorative design individual rooms. It is applied to the surface in the form of a pattern that appears only when the light is off. Professional designers recommend different shades for a variety of interior.

Main varieties

There is no officially accepted classification of this paint. But according to the type of active substance, the following types can be distinguished:

Fluorescent. Its glow appears only in ultraviolet rays. Often it is used in exterior design, nightclubs and car tuning. For her apply acrylic varnishes, which makes the enamel environmentally friendly for human health. Glow in the dark pigments can be of various shades. But the most spectacular are green, yellow, pink and red tones.

Luminescent. This is the most common paint that glows in the dark. She needs only 20 minutes of exposure to daylight or artificial light. Then surfaces are obtained that glow in the dark throughout the night. It is usually used as road markings or on barriers at construction sites. After application, photoluminescent paint significantly increases the safety of being at industrial facilities.

Phosphorizing. Due to the phosphorus content, it is hazardous to health. Because of this, it is rarely used and only for painting the external elements of buildings, cars. If possible, it is replaced with other types of finishes with luminous elements.

According to the degree of transparency of the pigment, translucent, almost invisible in daylight, and colored enamels are distinguished, which are visible in the daytime and have a wider color spectrum.

When choosing a paint, be guided by the coating material. For PVC surfaces, a dye with polyurethane-mineral resins is suitable, as they enhance adhesion. For painting flower beds, water-acrylic enamel is often used. It does not harm plants. Suitable for pools and drains waterproof base containing fluorescent ink.

Features of fluorescent paint

The paint is also called invisible or ultraviolet. Fluorescent ink prevents it from glowing on its own after dark. To get the light effect, exposure to ultraviolet light is required. When artificial light hits it, the usual appearance of the surface remains. The composition includes not only fluorescent ink, but also a transparent base.

Paint pigments are powdered dye, which is made of thermoplastic resins. Coloring composition Can be applied to glass, metal, wood, plastic and textile surfaces. It can even be applied to flowers that glow in the dark. The composition, including fluorescent ink, is non-toxic. It is completely safe for the health of people and animals, and is successfully used in the decoration of residential premises.

It is important to look at the name of the product and what composition it has. Luminous paint must have a production certificate and a safety data sheet. Beware of fakes as they can be too toxic due to a large number phosphorus in the composition.

Most convenient option is a spray can that is sprayed on almost all surfaces. Phosphorescent paint should be applied in an even layer on a flat and dry surface. It must be thoroughly mixed, because the phosphor may precipitate. Then it is better to apply a second layer. The interval between their coverage should be about 1.5 hours.

Electroluminescent paint is most pronounced on a plain surface with light shades. Therefore, in most cases, the surface is covered with white primer.

If you plan to use phosphorescent paints, take precautions. Phosphorus is extremely hazardous to health, so such compounds are used for the street or in a well-ventilated area. Wear gloves, goggles and a respirator.

Luminous paint is increasingly used in various areas, including interior decoration. When working, use certain proportions and keep a simple technological process. In this case, nothing will threaten your health, and the surface will be of high quality.

Hello! And I come to you with a wonderful interesting novelty from the Masura brand - emerging stamping inks.

A little from the manufacturer:

A novelty in the field of nail design - MASURA STAMP-INK disappearing stamping paints. Your manicure has long dreamed of such a highlight.
You are thinking whether to do a stamping or leave your nails covered with your favorite enamel red .... Do both. Apply MASURA STAMP-INK vanishing stamping ink to your favorite polish, top off with a top coat. And then ... Then in the sunlight, in warmth, in warm water, on the beach, your stamping design will disappear, and in the shade or in a cool room it will appear again. The stamping ink disappears and shows up even under the gel polish top.

Disappearing nail paints are suitable for beginners and experienced gourmands. Huge scope for your fantasies.

5 colors came to me for review: red Cherry, purple Pudding, green Lokum, orange Orange and silver Caprice.

The paints are enclosed in mini-bottles with a volume of 3.5 ml, that's how they are babies

Tassels - small but wide

And mini helpers - Top Fixer and Pink Cuticle Protector

My opinion: An interesting toy for big girls. The paints are rather weakly pigmented if applied in the usual way. More color is obtained if you use them as a basis for stamping or paint patterns. They become completely invisible only as one layer when stamping. With all other methods of application - poorly visible in a warm state. Color transitions happen pretty quickly. Definitely getting a lot of attention!

My use cases:

1. Use as a basis for stamping

I applied two coats of paint.

Turned almost white when warm

Put on a protective pink little thing

Made a stamping - in a warm state

Cold

Gradient

And this is how most often I saw a manicure (+ top). The top, by the way, lubricates the colors a little, but not critically.

Took a manicure for 3 days, then erased it.

2. Use as classic stamping inks

Applied paint - in a warm state are not visible

But in the cold they showed up - but the color is not so saturated. as you would like

Separately, I will show the Caprice paint (silver) - it did not disappear in a warm state (this is the classic version of the paint, not the one that appears).

3. So I decided to try using it on a dark background.

With pink stuff

Looks very cool! Matte paint. Does not disappear either in a warm or cold state.

I apologize for the greased ring finger (

I liked it best when used on a dark background.

4. I spied on other bloggers how they paint stamping with these paints and decided to repeat

hydrochromic ink. Volume in milliliters: 50. If you want to print specifically, then the paint is best suited for screen printing on fabric. Printing with such ink does not hold well on paper or plastic.

Unusual colors- these are not only those that, for example, glow in the dark, shine brightly in the ultraviolet, or, even more regrettable, are simply considered unusual just because of the shade or color. No, here you do not waste time in vain, the paint that can really be called unusual should have some properties, functionality or something.
So - this unusual paint is hydrochromic, i.e., changes its properties or color when interacting with water (MANY times!).
The paint discolors when water hits it. Initially, the paint has a white opaque color. But when water gets on the paint, it becomes completely transparent. Thus, paint can hide something, i.e. something will be painted over with a similar white paint, but when water gets in, the paint will become transparent, and what is under it will become visible.

The paint is reusable! Water enters - it becomes discolored, water dries up - it becomes opaque white. Volume: 50 ml. Screen printing is also possible.

Video:

There are others unusual colors, for example, which change their color from temperature changes or any other external factors, but about them another time.
You can find a lot of ways to use such paint, but some more playful options come to mind. For example, you can make fun of someone - drop such paint on any surface from which you can then clean it off, and admire what will happen to those who try to erase this white spot.
Approximately the following will happen: an unsuspecting person begins to erase the spot. He will take a piece of a rag, or simply moisten his hand with water, and begin to rub. You don’t have to rub for a long time, since the hand or rag will be wet, the stain will instantly discolor, i.e., for an unarmed person, it will simply disappear.
What a surprise it will be when the victim of the joke again finds a spot in the same place. I don’t advise anyone to mock relatives and friends like that, I don’t call for it at all, but what a pleasure it will be to watch, or better, to shoot this person who will erase the stain several times, then he will guard near this ill-fated place in order to prevent the stain from appearing again . How surprised the victim of the joke will be when he sees that right before her eyes, the spot appears again. Before a person begins to guess anything, he will definitely look up: "What if something is dripping from the ceiling ...?".

If anyone remembers, there used to be such toy chips for children. They were often played in schools, etc. On some chips, naked female bodies painted over with the same paint. When a teenager wetted the surface of the chip with saliva, the paint discolored, and the pattern located under it appeared.

You can use a similar paint to leave various secret messages to each other. For example, you write some text on a piece of paper regular pen or pencil, then paint over everything with this unusual paint. The recipient of the message will have to moisten a piece of paper with water, and the text will appear. After the water dries, the text will disappear again, because the paint is so easy to wipe off the paper with neither water nor a finger.

The process of fluorescence became known by George Stokes in the mid-nineteenth century. Its main meaning is that some substances can absorb light particles with one wavelength (energy), and emit with a shift towards longer wavelengths (energy reduction) due to nonradiative relaxation processes. The use of this phenomenon in the paint industry is reflected in a specific type of product - fluorescent paint.

What is fluorescent paint

Fluorescent effect paint has the ability to convert ultraviolet radiation with a shift into a spectrum visible to the human eye. Thus, under the influence of UV rays, the surface with such a coating begins to glow. rich color. In daylight, this paint gives a brighter and more noticeable color. At night, the paint can only glow under the influence of ultraviolet lamps.

Depending on the type of pigment, fluorescent paint is:

Visible - in the absence of ultraviolet radiation, it has its own color.
Invisible or colorless - does not have its own color, when exposed to ultraviolet light, it acquires a light blue, yellow, red, pink glow. A pigment can be used that only shines when exposed to a certain wavelength.

Fluorescent paint, unlike luminescent paint, is not able to autonomously glow in the dark after accumulating a charge from a light source.

Application of fluorescent paint

Fluorescent effect paint is widely used in various fields activities:

The perfect solution for outdoor advertising. Under influence daylight stands out and draws attention against the background of any other surrounding color. At night, with the help of illumination of ultraviolet lamps, it acquires a bright glow in the dark.
Used for original design solutions in entertainment centers, clubs, cafes.
For marking fences and parking lots, runways.
For artwork, painting, children's creativity.
For body painting (face painting, temporary tattoo).
For inscriptions on special vehicles, rolling stock.
In modeling and modding.
To create paintings with a fluorescent effect on concrete walls, stones, tiles. Creation of stained-glass windows and drawings on glass and ceramics.
For painting metal elements car bodies, disks - use aerosol paint in cans.
In the textile industry for dyeing fabrics, creating images and photos on T-shirts.
Stamp fluorescent ink for making invisible marks on cardboard and paper.
The fluorescence effect is used in the manufacture banknotes for counterfeit protection. If you illuminate such a banknote with an ultraviolet lamp, you can see signs that are invisible under ordinary light.

Ultraviolet radiation

The natural and most intense source of ultraviolet waves is sunlight. When passing through the atmosphere, only UVA radiation with a wavelength of 315-400 nm reaches the earth's surface (only a tenth is absorbed atmospheric layer) and a small part (about 10%) of UVB with a length range of 280-315 nm.

The level of UV radiation can be affected by:

The position of the Sun at a certain time of day and season.
Surface height above sea level.
The degree of cloudiness. Small clouds practically do not delay UV rays.
The thickness of the ozone layer.
Surface properties to reflect ultraviolet radiation.

In the shade, UV radiation is reduced by half or more, depending on the reflective properties of surrounding objects that are directly exposed to ultraviolet radiation. Snow is the most reflective and can reflect up to 90% of UV rays.

Luminous paints with a fluorescent effect: composition and application features

Fluorescence Properties paintwork gives a special pigment. It consists of particulate matter resins that are stained with fluorescent dyes (rhodamines and aminophthalimide derivatives). Pigments can be made for aqueous paintwork materials and solvent-borne systems, the latter being characterized by increased solvent and light resistance.

When mixing a paint material designed for certain types of surface with a compatible fluorescent pigment, a fluorescent paint is obtained. Thus, the pigment itself does not affect the scope and conditions for applying a film-forming fluorescent coating, it depends on the properties and purpose of the paintwork material. The most widespread received with a fluorescent effect.

The main disadvantage is poor resistance to direct sunshine which leads to rapid burnout. Overcome by applying additional transparent coatings with protective features. Another disadvantage is the difficulty of obtaining glossy finish due to the relatively large (up to 75 microns) size of the fluorescent pigment in the paint. It should be noted that the heat resistance of dyes is limited to 150-250°C.

Glow intensity at artificial lighting depends on the power of the UV lamps used, the number of layers applied and the color of the pigment (yellow, green, red have a higher saturation).

When preparing the surface for painting, except for traditional different types paint and varnish materials of action, manufacturers recommend covering the surface with a special primer paint white color. This enhances the fluorescent effect and reduces ink consumption.

For body art, a special mixture of fluorescent pigment with water, glycerin and lanolin is used. Before applying to the body, it is imperative to establish whether there is an allergic reaction to the coloring solution. To do this, a test smear is applied in the inner region of the elbow joint, if after half an hour there is no redness, then the paint can be applied to any part of the body. Wash off the paint with soap and water and special scrubs to completely cleanse the skin.

If fluorescent dye is used for outdoor work, then the freshly painted surface should be covered with an additional layer of varnish to increase the protective properties and resistance to direct sun rays which increases the service life of the coating. To avoid deterioration of the glow, do not use protective varnish with a matte finish.

DIY fluorescent paint

To make your own paint with a fluorescent effect, you need:

A clear lacquer designed for a certain type of surface.
Powdered fluorescent pigment.
Thinner suitable for the chosen varnish.
Glass container.

In a glass container, one part of the pigment is proportionally mixed to four parts of the varnish. For a more uniform distribution of the pigment and obtaining a uniform consistency, a solvent is added in small quantities. By changing the proportions, you can change the brightness and saturation of the glow, get more "poisonous" or "soft" colors. The resulting paint is applied to the surface in 3-4 layers.

The relative ease of manufacture and the growing popularity of fluorescent paint materials leads to wide choice products from different manufacturers. Positive reviews according to the price-quality parameter, art sets are received fluorescent paints Decola from the Nevskaya Palitra plant. For decorative and design work, it is profitable to buy a fluorescent acrylic enamel in spray cans trademark Kudo.
