    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: Various techniques are disclosed for forming bichromal balls or multicolored balls by laser-based methods. In one method, a laser and a template are used to form small discrete precursors that are subsequently spherodized. In another method a laser is used to cut or otherwise form small discrete precursors that are also subsequently spherodized. These methods are particularly well suited for forming balls or other sphere-like bodies having diameters less than 100 microns.
