Problems solved by technology

[0003] In recent years, in the field of color filter technology, the requirements for the performance of the formed pixels, black matrix, and colored radiation-sensitive composition have become more and more stringent. In addition to the sensitivity, resolution, and pattern shape of the colored radiation-sensitive composition, etc. In addition, solvent resistance to a wide range of solvents and excellent adhesion to substrates are also strongly required for pixels and black matrices. In addition, from the perspective of color filter production management, there is also a strong demand for color filters used in forming color filters. Colored radiation-sensitive compositions are strongly required to have excellent storage stability in the form of a solvent-containing liquid composition, but conventional colored radiation-sensitive compositions cannot sufficiently meet the above requirements.

Embodiment

[0340] Examples are given below to further specifically illustrate the present invention. The present invention is not limited by the following examples. Here, parts and % are based on weight.

[0341] Synthesis of Alkali Soluble Copolymer

Synthetic example 1

[0343] Add 3 parts of 2,2'-azobisisobutyronitrile, 200 parts of propylene glycol monomethyl ether acetate into a flask equipped with a condenser tube and a stirrer, then add 15 parts of methacrylic acid, 25 parts of 3-(methyl Acryloyloxymethyl)-3-ethyloxetane, 60 parts of benzyl methacrylate and 3 parts of α-methylstyrene dimer as a molecular weight regulator, replaced with nitrogen, and then gently Slowly stirring, the temperature of the reaction solution was raised to 80° C., and the temperature was maintained for 5 hours to perform polymerization to obtain a resin solution. This resin was referred to as "alkali-soluble resin (B-1)".

Synthetic example 2

[0345] Add 3 parts of 2,2'-azobisisobutyronitrile, 200 parts of propylene glycol monomethyl ether acetate into a flask equipped with a condenser tube and a stirrer, then add 15 parts of methacrylic acid, 25 parts of 3-(methyl Acryloyloxymethyl)-3-ethyloxetane, 20 parts N-phenylmaleimide, 10 parts styrene, 30 parts benzyl methacrylate and 3 parts as molecular weight regulator The α-methylstyrene dimer was replaced with nitrogen, then gently stirred, the temperature of the reaction solution was raised to 80° C., and the temperature was maintained for 5 hours to perform polymerization to obtain a resin solution. This resin was referred to as "alkali-soluble resin (B-2)".

Abstract

A radiation sensitive composition comprising a colorant, an alkali-soluble resin, a polyfunctional monomer and a photopolymerization initiator. The alkali-soluble resin is a copolymer of (b1) at least one first unsaturated compound selected from the group consisting of an unsaturated carboxylic acid, an unsaturated carboxylic anhydride and an unsaturated phenolic compound and at least one second unsaturated compound selected from the group consisting of (b2) an unsaturated compound having an oxetane skeleton and (b3) an unsaturated compound having a tetrahydrofuran skeleton. The radiation sensitive composition is used to form a colored layer.

Description

technical field [0001] The present invention relates to a radiation-sensitive composition for forming a colored layer, a color filter, and a color liquid crystal display element. More specifically, the present invention relates to a radiation-sensitive composition for forming a colored layer useful in a color filter used in a transmissive or reflective color liquid crystal display device, a color pickup tube element, etc. A color filter of a colored layer formed of a sensitive composition, and a color liquid crystal display element including the color filter. Background technique [0002] Conventionally, when a colored radiation-sensitive composition is used to manufacture a color filter, a method is known in which a colored radiation-sensitive composition is coated on a substrate or a substrate on which a light-shielding layer of a desired pattern is formed in advance, and then dried. Radiation is irradiated to dry coating film again, forms required pattern shape (hereinaf...
