Abstract: Disclosed are marking particles comprising a first polymer, a second polymer, a chelating agent, and a spiropyran material of the formula or wherein n is an integer representing the number of repeat -CH2- units and R is -H or -CH=CH2. The marking particles comprise a core containing the first polymer in which is dispersed the chelating agent and the spiropyran and encapsulated within a shell of the second polymer formulated by an Interfacial polymerization.

Abstract: A multicolored display and process for forming such a display is provide d. 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.
