摘要: Disclosed are marking particles comprising a first polymer a second polymer, a chelating agent, and a spiropyran material of the formula 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.

摘要: Disclosed is a display comprising an arrangement of a plurality of optically anisotropic rotatable elements, each of the rotatable elements having a surface in contact with an enabling fluid, the rotatable elements being electrically dipolar in the presence of the enabling fluid and thus being subject to rotation upon application of an electric field, the rotatable elements being free to rotate in place but not free to translate substantially so as to disrupt the arrangement of rotatable elements, wherein a first portion of the surface contains a mixture of a chelating agent and a spiropyran material of the formula wherein n is an integer representing the number of repeat —CH2— units and R is —H or —CH═CH2, and wherein a second portion of the surface contains substantially no spiropyran.

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.
