    摘要： A process comprising heating a mixture of colorant and latex in the presence of a coagulant and a silicate salt, and wherein said heating comprises a first heating equal to or below about the glass transition temperature of a polymer contained in said latex, and a second heating equal to or about the glass transition temperature of a polymer contained in said latex; wherein said first heating enables the formation of aggregates and said second heating enables the fusion of said colorant and said polymer; and optionally wherein said silicate is contained in an alkali metal hydroxide.

    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.
