Abstract: Radiation-setting compositions suitable for the formation of LCD spacers or protective layers which are excellent in photosetting properties (requiring no heat-setting) and development properties, have high adhesiveness to substrates and excellent mechanical characteristics, remain stable over a long storage time and show excellent working condition-dependency. Such a radiation-setting composition for the formation of LCD spacers or protective layers comprises a (meth)acrylic acid-based copolymer having an acid value of 30 to 200 and a glass transition temperature of −30 to 180° C., a (meth)acrylate-based compound obtained by copolymerizing a monomer having a specific structure with a monomer at least having an acidic group, a radiation-sensitive compound and a solvent.

Abstract: A material for forming a black matrix for a color liquid crystal display comprising: (A) an alkali-soluble resin obtained by the condensation reaction of phenols containing at least cresol with aldehydes; (B) an acid-crosslinkable methylolated melamine compound; (C) a compound which absorbs a light and then generates an acid; (D) a dispersant represented by formula (I): wherein R1 represents a straight chain or branched alkyl group having from 1 to 24 carbon atoms, and this alkyl group may have a substituent; R2 and R3 each represents a hydrogen atom or a methyl group; R4 represents a hydrogen atom, a straight chain or branched alkyl group having from 1 to 24 carbon atoms, —COR5 or —CONR6, and this alkyl group may have a substituent; R5 and R6 each represents an alkyl group having from 1 to 12 carbon atoms, an aryl group having from 6 to 12 carbon atoms, or an alkenyl group having from 6 to 32 carbon atoms; m represents 0, 1 or 2; n represents 1, 2 or 3, provided that m+

Abstract: A photosensitive colored composition for a color filter is described, which comprises (A) a pigment, (B) a binding resin, (C) a radiation-sensitive compound, and (D) a solvent, wherein (A) a pigment contains a pigment having an average particle size of from 0.01 to 0.2 .mu.m represented by formula (I): ##STR1## wherein Y represents an oxygen atom or a sulfur atom; R.sub.1 and R.sub.2, which may be the same or different, each represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aryl group, an aralkyl group, a carbamoyl group, an alkylcarbamoyl group, an arylcarbamoyl group, or an alkoxycarbonyl group; and R.sub.3 and R.sub.4, which may be the same or different, each represents an alkyl group, a cycloalkyl group, an aralkyl group, or a carbocyclic or heterocyclic aromatic residue.

Abstract: A radiation sensitive colored composition comprising (A) a copolymer having, as constitutional repeating units, at least ((1) a monofuctional macromonomer having the specified structure and weight-average molecular weight of 3.times.10.sup.4 or below, (2) a monomer having the specified structure and (3) a quaternary ammonium salt monomer; (B) a radiation sensitive compound; and (C) a pigment: which can provide a color filter having excellent pattern reproducibility because of its high suitablity for dispersion of fine-grain pigment and its high storage stability.
