    摘要： A multicolored display and process for forming such a display is provided. The multicolored display includes marking particles comprising a mixture of photochromic materials. The photochromic materials each exhibit a first “invisible” photochromic state at a first absorption spectrum and at least a second “visible” photochromic state at a second absorption spectrum. The second “visible” photochromic state of each photochromic material produces a different color relative to the other photochromic materials. In embodiments, the marking particles include a mixture of a spiropyran material and a dithienylethene material.
