Synthetic example 1

[0146] 120 parts by weight of propylene glycol monomethyl ether acetate, 80 parts by weight of propylene glycol monomethyl ether, 2 parts by weight of azobisiso Butyronitrile (AIBN), 13.0 parts by weight of acrylic acid, 10 parts by weight of benzyl methacrylate, 57.0 parts by weight of 4-methylstyrene, 20 parts by weight of methyl methacrylate, 3 parts by weight of n-dodecyl Alkylthiols with nitrogen replacement. After that, stirring was performed, and the temperature of the reaction liquid was raised to 110° C., and the reaction was performed for 6 hours. The solid content of the alkali-soluble resin thus synthesized had an acid value of 100.2 mgKOH / g, and a weight average molecular weight Mw measured by gel permeation chromatography (GPC) was about 15,110.

Abstract

The invention relates to a colored photosensitive resin composition for a color filter, a color filter and a liquid crystal display device having the same, concretely a colored photosensitive resin composition for a red filter used in manufacturing a red filter used for a color LCD display unit.

Description

technical field [0001] This invention relates to a colored photosensitive resin composition. More specifically, it is related with the colored photosensitive resin composition for red color filters used when manufacturing the red color filter used for a color liquid crystal display etc. Background technique [0002] Recently, with the demand for high color reproduction of color filters for liquid crystal displays (LCDs), the content of the coloring material in the colored photosensitive resin composition used in the production of color filters has continued to increase. In addition, in order to manufacture high-quality color filters excellent in visibility, there is a continuous demand for improvement in contrast. [0003] However, in the conventional pigment dispersion system, the pigment content in the colored photosensitive resin composition is reaching the limit, and the improvement of the contrast by micronization of the pigment is also reaching the limit. Currently, m...
