Abstract
The invention discloses a photochromic dope which contains the necessary components of a normal dope. The invention is characterized in that the colorant of the dope consists of an inorganic dye and an organic dye; the color of the inorganic dye and the color of the organic dye are complemental; under the state of normal light or weak light, the dope shows to be white, gray or colorless; the color of the inorganic dye is not affected by the sunshine basically; while the organic dye is an allochroic dye which is affected by the sunshine. The photochromic dope has the beneficial effects that: the dope is white, gray or colorless under the normal or weak light as well as has plump colors and good chroma maintenance; after being shined by strong light, the dope shows another color; when the illumination is weakened, the dope resumes to be white, gray or colorless again. The dope can reduce the aesthetic tiredness as well as can bring novel and special effects.
Description
Technical field:
The present invention relates to coating, specifically, is an a kind of class photochromic coating that comprises the coating on the common meaning, paint and printing ink etc.
Background technology:
Existing coating (comprising coating, paint, printing ink etc.) is generally color invariable (as white or colourless), and visible changes just, subtracts light, yellowing or contaminated variable color, eye strain easily in time.Other has the coating of thermochromism, and its tinting material is a certain pigment or a certain dyestuff, owing to the variation of envrionment temperature causes variable color.Photochromic coating is also arranged, and its tinting material is a certain dyestuff, and color and luster is full inadequately, and the colourity retentivity is bad.
Summary of the invention:
Purpose of the present invention: enrich coating (comprising coating, paint, printing ink) market product structure, provide a class reversible change photochromic coating can take place by the variation of light, by white, grey or colourless (initial look) with coloured between conversion mutually.
Technical solution of the present invention is: a kind of coating, contain the neccessary composition of conventional coating, and colorants for paints is made of jointly mineral dye and organic dye; The color of mineral dye is the complementary color of pigment dyestuff color, or is the Similar colour of complementary color, or is the look that closes on of complementary color.Under ordinary light or the low light level state, coating display white, grey or colourless.And the color of mineral dye is not subjected to sun-exposed the influence substantially; And organic dye is to be subjected to the influence of irradiate light and the dyestuff of variable color.
In ordinary ray or high light line when irradiation on the same day, coating of the present invention (coating, paint, printing ink) is by white, grey or colourlessly become another kind of color; More weak or when being day ordinary ray, coating (coating, paint, printing ink) reverts to white, grey or colourless again when light.
The influence that is subjected to irradiate light described in the present invention and the organic dye of variable color is divided into two kinds of situations by the light difference:
1) under low light level state for the look that closes on of the Similar colour of the complementary color of mineral dye color, complementary color or complementary color, under the ordinary light irradiation, become another kind of color;
2) under the ordinary light state for the look that closes on of the Similar colour of the complementary color of mineral dye color, complementary color or complementary color, under strong illumination, become another kind of color.
Among the present invention, the consumption of mineral dye and organic dye is suitable substantially, and promptly the colourity before the colourity that produces of mineral dye and the organic dye variable color is suitable, and the color after the stack be a white or approaching white or colourless.
Among the present invention, mineral dye is the pigment of common inorganic substance.
Among the present invention, organic dye is a class organic polymer dyestuff, on this high molecular main chain or the side chain photochromic group is arranged, perhaps the organic dye blend another kind contain the macromolecular material of photochromic group.This family macromolecule comprises that containing first presses by structure-type, sulfur-bearing snap hydrazone structure-type, nitrogen benzide type, poly-dipyridyl type, contains indenes diketone structure type, contains the thiazine structure-type, contains spiral shell structure-type or the like.
Light causes that photochromic group produces reversible photochemistry variable color process, optical physics variable color process or two kinds of processes and all has.
The variable color of the organic dye among the present invention also can be that the rayed by certain particular range of wavelengths such as infrared, ultraviolets causes.
The consumption of the organic dye among the present invention can be a little more than mineral dye, to eliminate the stable inadequately defective of organic dye color and luster.
Among the present invention, also can be added with the stablizer of organic dye, to reach stable color effect.
Advantage of the present invention: under the coating ordinary light or the low light level, be white, grey or colourless, color and luster is full, and the colourity retentivity is good; After being subjected to strong illumination, coating is shown as another kind of color; After illumination weakens, revert to white, grey or colourless again.This class coating can reduce aestheticly tired, brings novel and special effects, enriches the market of coating (coating, paint, printing ink); And can bring novel and special effects, make the printing ink of latent type under the ordinary light, illumination display text picture.
Description of drawings
Accompanying drawing 1 is colour circle figure, among the figure 1, the color of mineral dye; 2, the diameter of colour circle; 3, the colour circle center of circle; 4, the color that shows before the organic dye rayed; 4 is 1 complementary color.
Accompanying drawing 2 is the priming color stacking diagram, among the figure 1, the mineral dye color; 2, colour mixture (white, grey or colourless); 3, organic dye color; 3 is 1 complementary color.
Specific embodiment
Get the blue mineral dye of Mi Luoli of 1 part of blue look, 1 part of orange contain thiocarbazone sulfocarbazone structure-type high molecular dye, other moietys of some parts of coating, mixing in solvent is modulated to the coating of colourless (showing during the low light level).After the white wall that this coating is coated, accept the intensive sun exposure, contain thiocarbazone sulfocarbazone structure-type polymer and become purple by orange, the wall of this moment is shown as mixture colors--the bluish voilet after the variable color.After the sun sets, contain thiocarbazone sulfocarbazone structure-type polymer and become orange by purple, wall reverts to original mixture colors again--white, grey or colourless.
Claims (7)
