Abstract
Provided is a colored curable composition having a good chemical resistance, and capable of forming a good colored layer pattern, the colored curable composition including an epoxy group-containing compound, and a phthalocyanine dye having a functional group capable of forming a covalent bond by a reaction with the epoxy group under heating.
Claims20
A colored curable composition comprising an epoxy group-containing compound and a phthalocyanine dye having a functional group capable of forming a covalent bond by a reaction with the epoxy group under heating.
A colored curable composition comprising an epoxy group-containing compound, and a phthalocyanine dye having a functional group,
- wherein the functional group is at least one species selected from a carboxyl group, an epoxy group, an aryl ester group, a tertiary alkyl ester group, a group represented by the formula (1), a group represented by the formula (2), amino group and a thiol group;
- wherein R1 represents a fluorine atom-containing alkyl group;
- wherein each of R2 and R3 independently represents an alkyl group, and R2 and R3 may combine with each other to form a ring.
A method for manufacturing a color filter, the method comprising:
- forming a colored layer by curing a colored curable composition which contains a phthalocyanine dye having a functional group capable of forming a covalent bond by a reaction with an epoxy group under heating, and an epoxy group-containing compound;
- forming a photoresist layer on the colored layer;
- obtaining a resist pattern by patterning the photoresist layer by exposure and development;
- and
- dry-etching the colored layer using the resist pattern as an etching mask.
