Problems solved by technology

[0005] However, in conventional radiation-sensitive compositions used for color filter formation, including that described in JP-A-2001-235617, in preventing the sublimation of the radiation-sensitive polymerization initiator component, the sintering furnace and the photomask It cannot be said that it is sufficient in terms of pollution and the formation of impurities in the liquid. Therefore, it is currently strongly desired to develop a radiation-sensitive composition that has these characteristics.

Synthetic example 1

[0286] In a flask equipped with a cooling tube and a stirrer, add 1 part by weight of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by weight of propylene glycol monomethyl ether acetate, and then add 15 parts by weight of methacrylic acid, 15 parts by weight of styrene, 35 parts by weight of benzyl methacrylate, 10 parts by weight of glycerol monomethacrylate, 25 parts by weight of N-phenylmaleimide and chain transfer agent α- After replacing 2.5 parts by weight of methylstyrene dimer with nitrogen, the mixture was slowly stirred, the temperature of the reaction solution was raised to 80° C., and the temperature was maintained for 3 hours for polymerization. Then, the temperature of the reaction solution was raised to 100°C, 0.5 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile) was added, and polymerization was carried out for 1 hour to obtain (B) an alkali-soluble resin Solution (solid content concentration=33.0% by weight).

Abstract

A dyed layer forming used sense radiating linear composition includes a colorant, an alkali-soluble resin, a polyfunctional monomer and the sense radiating linear polymerization initiator of 2-(4-methy benzyl)-2-(dimethylamino)-1-(4-mrpholine phenyl)butane-1-ketone kind of mrpholine phenyl compound. The composition can restrain the pollution to the sintering furnace and photomask which is caused by the sublimation of the sense radiating linear polymerization initiator component, furthermore, the liquid is not generated with impurity and the imaging property and pattern shape are excellent.

Description

technical field [0001] The present invention relates to a radiation-sensitive composition for forming a colored layer, a color filter, and a liquid crystal display, and more particularly relates to a color filter used in a transmissive or reflective color liquid crystal display device, a color imaging tube element, and the like. A radiation-sensitive composition for forming a colored layer, a color filter having a colored layer composed of the radiation-sensitive composition, and a liquid crystal display having the color filter. Background technique [0002] Conventionally, when a color filter is manufactured using a coloring radiation-sensitive composition, it is known to coat a coloring radiation-sensitive composition on a substrate or a substrate on which a light-shielding layer of a predetermined pattern has been formed in advance, and to face the coating film after drying. A method of forming pixels of each color by irradiating radiation (hereinafter referred to as expo...
