Abstract
A radiation-sensitive composition which comprises (A) a binder polymer which is a copolymer comprising (A-1) a monomer containing an alcoholic hydroxyl group, (A-2) a macromonomer, and (A-3) other monomer copolymerizable with the above monomers; (B) a pigment, and (C) a radiation-sensitive compound. This radiation-sensitive composition is suited as a color-dispersed composition for a color filter which does not cause surface soiling and which has an excellent adhesion of a formed pixel to a glass substrate.
Claims8
A radiation-sensitive composition, which comprises:
- (A) a binder polymer which is at least one member selected from the group consisting of
- a 2-hydroxypropyl(meth) acrylate/polystyrene macromonomer/benzyl methacrylate/methacrylic acid copolymer,
- a 2-hydroxy-3-phenoxypropyl acrylate/polymethylmethacrylate macromonomer/benzyl methacrylate/methacrylic acid copolymer, and
- a 2-hydroxyethyl methacrylate/polystyrene macromonomer/benzyl methacrylate/methacrylic acid copolymer;
- (B) a pigment;
- (C) a radiation-sensitive compound, comprising:
- (C-1) a combination of:
- (C-1-a) a radiation-polymerization initiator, and
- (C-1-b) a radiation-polymerizable monomer or oligomer, or
- (C-2) a radiation crosslinking agent;
- and optionally,
- (D) an organic carboxylic acid containing at least one acid group in the molecule and having a molecular weight of 1,000 or less.
