Abstract: PROBLEM TO BE SOLVED: To form an image forming material having high resolution and surface smoothness, and restrain the occurrence of projections from the surface of the image forming material by specifying the angle of contact of methylene iodide for a hardened film cured under exposure to a radiation. SOLUTION: This radiation sensitive composition used for a color filter is prepared so as to contain a coloring agent A, a binder polymer B, a multifunctional monomer C, a photochemical polymerization initiator D, a solvent E and a surface active agent F, and to have an angle equal to or less than 55 degrees as the angle of contact of methylene iodide for a hardened film cured under exposure to a radiation. In other words, the angle of contact of methylene iodide for the hardened film cured under exposure to a radiation is equal to or less than 55 degrees and in particular, when a red coloring agent is used as an A-component, the angle of contact of methylene iodide for the obtained hardened film is preferably taken at 45 degrees or less. Also, when a green or blue coloring agent is used as the A-component, the angle of contact of methylene iodide for the obtained hardened film is preferably taken at 50 degrees or less.

Abstract: PROBLEM TO BE SOLVED: To provide an innovative radiation-sensitive composition for a color filter which can provide excellent developing property even in the case pigments are mixed in high concentration and excellent pixels with high adhesion strength to a substrate and a light shielding layer and causes no residue and surface contamination on non-radiated parts of the substrate and the light shielding layer at the time of development. SOLUTION: This radiation-sensitive composition for a color filter consists of (A) coloring agents, (B) an alkali-soluble resin containing copolymer of a monomer having a defined formula and another copolymerizable monomer, (C) a multi-functional monomer, and (D) a photo polymerization initiator. In the formula, R stands for hydrogen atom or methyl group; m for an integer from 1 to 10; and n for an integer from 1 to 4.

Abstract: PROBLEM TO BE SOLVED: To provide an alkaline developer for a radiation sensitive compsn. which leaves no undissolved material even when the concn. of a pigment contained in the compsn. is high, does not cause problems such as the occurrence of scum, incomplete development and resticking and can form a pixel having sharp pattern edges. SOLUTION: This alkaline developer comprises an aq. soln. contg. at least one inorg. alkaline compd. and at least one org. alkaline compd. selected from the group consisting of alkanolamines and alkylamines or further contains at least one nonionic surfactant selected from the group consisting of etherified polyoxyethylenes and etherified polyoxyethylene-polyoxypropylene block copolymers.

Abstract: PROBLEM TO BE SOLVED: To prevent the residue of an unexposed part on a substrate or on a light-shielding layer and contamination of a base during development and to obtain pixels excellent in adhesion property to the substrate and the light- shielding layer by using a specified alkali-soluble resin containing a copolymer. SOLUTION: This radiation-sensitive compsn. for a color filter contains a coloring agent, an alkali-soluble resin containing a copolymer of a monomer expressed by the formula and another copolymerizable monomer, polyfunctional monomers, and a photopolymn. initlator. In the formula, R is a hydrogen atom or methyl group. As for another copolymerizable monomer, it is not specified as far as it copolymerizes with the monomer expressed by the formula and that the produced polymer is soluble with alkali. Especially, a monomer mixture comprising an ethylenic unsatd. monomer having one or more carboxyl groups and other copolymerizable ethylenic unsatd. monomer is preferably used. The polymn. proportion of the monomer in the copolymer is usually 5 to 35 wt.%, preferably 10 to 25 wt.%.
