Abstract

Disclosed is a colored curable composition for color filters, which contains (1) at least one alkali-soluble resin selected from (meth)acrylic copolymers having an alicyclic (meth)acryloyl group in aside chain and copolymers having 0.001-0.20 eq/g of a (meth)acryloyl group and an acid value of 10-150, (2) a photopolymerization initiator, (3) a polymerizable monomer or oligomer having a partial structure selected from a urethane, an amide and a urea, and an ethylenically unsaturated double bond, and (4) a coloring agent. Also disclosed is a colored curable resin composition containing (a) a coloring agent, (b) a compound having at least one ethylenically unsaturated double bond, (c) a binder resin containing a (meth)acrylic copolymer having an alicyclic (meth)acryloyl group in a side chain, (d) a photopolymerization initiator, and (e) a compound having at least one ethylenically unsaturated double bond and a partial structure selected from a urethane, an amide and a urea in a molecule.

Description

technical field [0001] The present invention relates to a curable composition for a color filter suitable for producing a color filter used in a liquid crystal display element or a solid-state imaging element, a color filter, and a method for producing the same. [0002] Furthermore, the present invention relates to a colored curable composition, a colored pattern forming method, a colored pattern, a method for producing a color filter, a color filter, and a liquid crystal display element. Background technique [0003] A color filter is an indispensable component of a liquid crystal display or a solid-state imaging device. Liquid crystal displays are more compact than CRTs, and are equal to or higher in performance. Therefore, they are replacing CRTs as television screens, computer screens, and other display devices. In addition, in recent years, the trend of development of liquid crystal displays is shifting from the conventional monitor use with a relatively small screen ...
