[0145] Manufacture of Pigment Dispersion Compositions

[0146]

[0147] 10.85 parts by weight of C.I. Pigment Red 254, 3.80 parts by weight of AJISPUR PB821 (manufactured by Ajinomoto FineTechno Co., Ltd.) as a dispersant, 76.90 parts by weight of propylene glycol monomethyl ether acetate as a solvent, and 8.45 parts by weight of The cyclohexanone was mixed and dispersed for 12 hours, thereby producing the pigment dispersion liquid M1.

[0148] Synthesis of Alkali Soluble Resin

Synthetic example 1

[0150] 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.

[0151] Manufacture of colored photosensitive resin composition

Embodiment 1

[0153] Mix the above-mentioned of 36.50 weight parts, the acid red (Acid Red 52, TCI America company) of 0.54 weight parts, the resin of of 10.11 weight parts, the KAYARAD DPHA of 3.86 weight parts (Japan Kayaku Corporation), 1.00 parts by weight of TR-PBG-305 (manufactured by TRONLY Corporation), 0.23 parts by weight of 1,3,5-trimethyl-2,4,6-tris(3 ,5-di-tert-butyl-4-hydroxybenzyl)benzene (1,3,5-Trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene) (240 hours, Aldrich Company), 0.15 parts by weight of triphenyl phosphate (Triphenyl phosphate) (Aldrich Company), 12.75 parts by weight of 4-hydroxyl-4-methyl-2-pentanone , 34.85 parts by weight of propylene glycol monomethyl ether acetate to manufacture a colored photosensitive resin composition.

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] The present invention relates to a colored photosensitive resin composition. More specifically, it relates to a colored photosensitive resin composition for a red color filter used when producing a red color filter used for a color liquid crystal display device or the like. Background technique [0002] Color filters are widely used in plasma display panels (PDPs), liquid crystal displays (LCDs), field emission displays (FELs), and light emitting diode displays (LEDs), and the range of applications of color filters is rapidly expanding. In particular, the use in LCDs has been further expanded recently, and therefore, color filters are considered to be one of the most important components in reproducing the color tone of LCDs. [0003] Such a color filter is manufactured by a method of forming a desired colored pattern using a colored photosensitive resin composition containing a colorant. Specifically, by repeatedly performing a series of processes su...
