Description
Technical Field
The application relates to the technical field of optical anti-counterfeiting, in particular to a coating composition.
Background
The structural color is generated by the phenomena of interference, diffraction, scattering or absorption of incident light caused by the fine microstructure of the material. Because the optical phenomenon is determined by the characteristics of the material, the material is not easily influenced by external environment, so that the structural color is more stable than the traditional pigment color, and the service life is longer. In recent years, the anti-counterfeiting agent has been widely applied to industries such as automobile paint, decoration, printing, cosmetic and anti-counterfeiting.
At present, most of main structural color materials are sheet-shaped optical materials or photonic crystals, and the material arrangement optical interference, specific size and regular arrangement are mainly utilized to obtain the multi-beam interference or diffraction effect, so that the photonic crystal material presents specific colors. However, most of the existing structural pigments are changed into colors, and the change effect is more conventional and has no obvious difference. Specific variations, such as black to color, are sought in order to achieve differentiation, uniqueness.
In the prior art, black color change is achieved by characteristic absorption by combining a selective absorbing material with optically variable pigments, for example, patent document CN101171099B, but the selective absorbing material has a severe process and poor environmental suitability due to its own characteristics. The other part realizes achromatic to chromatic color change through pigment structural design, for example, patent document CN111965748A, but the structural technology is suitable for changing silver, silver ash and the like into chromatic color, and the black color change can be realized only by introducing other special material processes, so that the technology is complex, the cost is higher, and the color effect is poor.

Color is understood to mean that the C color saturation is greater than 20 under the CIE1964 system.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a coating composition provided herein, and specifically, the coating composition 10 includes: the coating composition 10 has the advantages of simple structure, easy preparation and low cost, and is characterized by comprising the characteristic optically variable pigment 11 and the transparent resin 12, wherein the transparent resin 12 is coated on the outer surface of the characteristic optically variable pigment 11.
The coating composition 10 composed of the characteristic optically variable pigment 11 and the transparent resin 12 has a number of reflection peaks of at least 2 when the observation angle is deviated from 0 degrees with respect to the normal direction of the main surface of the coating composition 10 in the range of visible light having a wavelength of 380nm to 780nm, wherein the reflection peak of the coating composition 10 has a peak reflectance of 10% or more and 40% or less, the average reflectance of the coating composition 10 in the visible light range is less than 20%, and the spectral reflection peaks of the coating composition 10 are in a complementary color decolored balanced state, whereby a black effect at a viewing angle of 0 degree can be achieved. The coating composition is colored when the viewing angle deviates by more than 30 degrees in the normal direction relative to the major surface of the coating composition 10.
That is, the coating composition 10 of the above embodiment can realize black at a viewing angle of 0 degrees, and various colors such as green, red, yellow, blue, violet, etc. can appear at a viewing angle of more than 30 degrees. Wherein a viewing angle of 0 degrees means that the viewing angle is offset by 0 degrees with respect to the normal direction of the major surface of the coating composition 10, i.e., the viewing direction is the normal direction of the major surface of the coating composition 10. Viewing angles greater than 30 degrees refer to viewing angles that deviate by greater than 30 degrees from normal to the major surface of the coating composition 10.
Since the refractive index of the transparent resin 12 is larger than that of air and smaller than that of the outer surface of the characteristic optically variable pigment 11. The present application utilizes the refractive index of the transparent resin 12 to adjust the spectral distribution of the characteristic optically variable pigment 11 so as to achieve that the coating composition 10 is black when viewed at an angle of view that deviates from 0 degrees with respect to the normal direction of the major surface of the coating composition 10, and colored when the angle of view deviates by more than 30 degrees with respect to the normal direction of the major surface of the coating composition 10.

The transparent resin 12 is mainly used for balancing the refractive index and adjusting the visible light reflection spectrum distribution of the characteristic optically variable pigment 11. The transparent resin 12 includes, but is not limited to, acrylic resin, polyurethane resin, and the like.
Further, in the range of visible light having a wavelength of 380nm to 780nm, when the observation angle is deviated from 0 degrees with respect to the normal direction of the main surface of the characteristic optically variable pigment 11, the number of reflection peaks of the characteristic optically variable pigment 11 is at least 2, wherein the peak reflectance of the reflection peaks of the characteristic optically variable pigment 11 is 10% or more and 40% or less, the average reflectance of the characteristic optically variable pigment 11 is less than 15%, and the distribution of the reflection peaks of the characteristic optically variable pigment 11 includes complementary color gamut combinations, that is, complementary color gamuts appear in pairs. For example, red-green, blue-orange, violet-yellow, etc., the characteristic optically variable pigment 11 has a reflection peak in one of the color gamuts, and then the complementary color gamuts must have another complementary color peak, and the color gamuts, when combined with the transparent resin 12, reach an achromatic balance state.

The complementary colors of the reflection peaks blue and yellow appear in a pair combination and are in a decolored equilibrium state, the average reflectivity of the coating composition 10 is less than 20%, the observation effect at a viewing angle of 0 degrees is black, and the decolored equilibrium state is broken to appear green when the observation angle is more than 30 degrees.

The material of the metal layer 113 may be metal or metal compound. For example, the material of the metal layer 113 includes at least one of aluminum, titanium, iron, nickel, chromium, germanium, tungsten, gold, silver, copper, platinum, and palladium, or an alloy of at least one of them.
