Abstract
A process is provided for producing a radiation sensitive composition for color filters. The process comprises (1) dispersing a pigment (A) in a solution of an alkali-soluble resin (B) dissolved in a solvent (E) to form a pigment dispersion; and (2) adding and mixing a polyfunctional monomer (C) and a photopolymerization initiator (D) with said pigment dispersion to form the radiation sensitive composition. The color filter is useful for a color liquid crystal display element.
