Reversible temperature sensitive color pigments are prepared by electron transfer organic compounds. Electron transfer organic compounds are a kind of organic color system with special chemical structure. At a given temperature, the molecular structure of the organic material is changed due to electron transfer, and the color change is realized. This discoloration not only bright colors, but also can realize the change from "color = colorless" and "colorless = coloured" state of color, this is a heavy metal salt complex type and type of reversible thermochromic liquid crystal material not available.
