Abstract
Compositions for making structured color images comprising (a) a soluble pigment precursor which can be transformed to an insoluble pigment by means of chemical, thermal, photolytic or radiation-induced method, and (b) a binder polymer or prepolymer, or a positive or negative resist-type resin which can be structured by crosslinking, polymerization or depolymerization by applying heat or electromagnetic irradiation. The compositions can be applied to optical and thermal recording, printing, and the production of color filters for Liquid Crystal Displays, with high accuracy, high transparency and high stability.
Claims22
A composition for making a patterned color image comprising
- (a) a pigment precursor which is dissolved in said composition and which can be transformed into a pigment which is insoluble in the color image by the action of an acid or base or by heating to a temperature of 130.degree.-200.degree. C. or electrornagnetic irradiation, or a combination thereof;
- and
- (b) a positive or a negative photoresist, which is made from a resin, polymer or prepolymer, and the structure of which can be modified by crosslinking, polymerization or depolymerization by applying UV or visible light, alone or in combination with heating to a temperature up to 120.degree. C.
