Laser paste is also called rainbow paste. It is a high-grade optically variable pigment. It is composed of nanometer-thick flake metal particles. The surface is specially treated with The inks and paints prepared by it can show different colors as the viewing angle changes, with obvious dynamic discoloration effect, and can produce a rainbow phenomenon under direct light.
The discoloration principle and characteristics of laser paste
Laser paste is a new generation of color-changing pigment, and its color-changing principle is different from that of chameleon. Rainbows (rainbows) in nature are a phenomenon of light change. When sunlight shines on water droplets in mid-air, the light is refracted and reflected, forming an arched colorful spectrum. The discoloration principle of laser slurry is similar to that of Yuhong. It uses laser etching to form a concave and convex structure on the surface of thin metal/compounds. When small flakes with this structure are arranged on the surface, a discoloration phenomenon occurs. Compared with chameleons, laser discoloration has bright and colorful colors. Generally speaking, it has three major characteristics: 1. Different angle discoloration, that is, different colors appear at different viewing angles; 2. Rainbow ring phenomenon appears under direct light, so it is also called rainbow slurry pigment. ③The stronger the light, the brighter the color.
