Abstract
Official abstract text for this publication.
A method of producing a color filter includes (a) forming a colored pattern on a substrate by exposing and developing a colored curable composition containing a dye, a polymerizable monomer and an organic solvent, (b) forming a transparent protective film on the colored pattern, and (c) irradiating at least the transparent protective film with light after forming the transparent protective film on the colored pattern.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing a color filter comprising: (a) forming a colored pattern on a substrate by exposing and developing a colored curable composition comprising a dye, a polymerizable monomer and an organic solvent; (b) forming a transparent protective film on the colored pattern by using a transparent curable composition composing a photopolymerization initiator, a polymerizable unsaturated compound and an organic solvent, wherein the photopolymerization…
