Novel thermochromic and/or photochromic compositions are described. The thermochromic compositions include a thermoset resin, cholesterol, water, and dye, while photochromic compositions include a benzene and a binder, such as silica gel. When mixed, the ingredients of the thermochromic and photochromic compositions form chromic cells with an outer shell comprised of either the thermoset resin (in the case of thermochromic compositions) or potassium nitrate (in the case of photochromic compositions). When the chromic compositions are exposed to either a heat or light stimulus, the chromic cells compress to causing the dye within the cells to no longer be visible, thereby creating a color-changing effect.
本文描述了新型热致变色和/或光致变色组合物。热致变色组合物包括热固性树脂、胆固醇、水和染料,而光致变色组合物包括苯和粘合剂,如硅胶。热致变色组合物和光致变色组合物的成分混合后会形成铬电池,其外壳由热固性树脂(热致变色组合物)或硝酸钾(光致变色组合物)组成。当色素组合物受到热或光的刺激时,色素细胞会压缩,使细胞内的染料不再可见,从而产生变色效果。
