Problems solved by technology

Furthermore, in the prevention of "afterimage", it is known that improving the purity of the pigment is effective as disclosed in JP 2000-329929 A, but impurities may also originate from other than the pigment in the radiation-sensitive resin composition. components, simply improving the purity of the pigment may not be sufficient

Embodiment

[0305] Hereinafter, an Example is given and the embodiment of this invention is demonstrated more concretely. However, the present invention is not limited to the following examples.

[0306] Mw and Mn of the resins obtained in the following Synthesis Examples were measured by gel permeation chromatography (GPC) of the following specifications.

[0307] Device: GPC-101 (manufactured by Showa Denko Co., Ltd.).

[0308] Column: GPC-KF-801, GPC-KF-802, GPC-KF-803 and GPC-KF-804 are used in combination.

[0309] Mobile phase: tetrahydrofuran containing 0.5% by weight phosphoric acid.

Synthetic example 1

[0311] Add 10 parts by weight of 2,2'-azobisisobutyronitrile and 400 parts by weight of dipropylene glycol dimethyl ether into a flask equipped with a condenser tube and a stirrer, then add 20 parts by weight of methacrylic acid, 31.2 parts by weight of N -Phenylmaleimide, 30 parts by weight benzyl methacrylate, 18.8 parts by weight styrene and 10 parts by weight α-methylstyrene dimer (molecular weight control agent), carry out nitrogen replacement, and then slowly While stirring, 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, 2 parts by weight of 2,2'-azobisisobutyronitrile was added, and polymerization was continued for 1 hour to obtain a resin solution (solid content = 20.1% by weight). Mw=5,000 of this resin, Mw / Mn=3.6. This resin was referred to as resin (β-1).

Synthetic example 2

[0313]Add 2.5 parts by weight of 2,2'-azobisisobutyronitrile and 200 parts by weight of dipropylene glycol dimethyl ether into a flask equipped with a condenser tube and a stirrer, then add 20 parts by weight of methacrylic acid, 31.2 parts by weight of N -Phenylmaleimide, 30 parts by weight benzyl methacrylate, 18.8 parts by weight styrene and 3 parts by weight α-methylstyrene dimer (molecular weight control agent), carry out nitrogen replacement, and then slowly While stirring, 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'-azobisisobutyronitrile was added, and polymerization was continued for 1 hour to obtain a resin solution (solid content = 33.2% by weight). Mw=14,000 of this resin, Mw / Mn=2.1. This resin was referred to as resin (β-2).

Abstract

The present invention provides a radiation-sensitive resin composition comprising (A) a colorant, (B) an alkali-soluble resin, (C) a polyfunctional monomer, and (D) a radiation-sensitive radical generator, wherein the alkali-soluble resin (B) is a resin having a dithiocarbonyl-containing group at at least one end. This composition can give color filters free from image persistence in a high yield.

Description

technical field [0001] The present invention relates to a radiation-sensitive resin composition useful in the preparation of color filters for use in transmissive or reflective color liquid crystal devices, color imaging tube elements, etc., its preparation method, and products formed from the radiation-sensitive resin composition A color filter and a color liquid crystal display device provided with the color filter. Background technique [0002] As a method of forming a color filter using a colored radiation-sensitive resin composition, it is known to form a coating film of a colored radiation-sensitive resin composition on a substrate or a substrate on which a light-shielding layer of a predetermined pattern has been formed in advance, via A method in which a pattern-shaped photomask is irradiated with radiation (hereinafter referred to as "exposure"), developed with an alkaline developer, and the unexposed part is dissolved and removed, and then post-baked using a clean ...
