Embodiment approach

[0034]

[0035] The colored photosensitive resin composition of the present invention contains an alkali-soluble resin (A). Of course, the composition of the present invention may also contain a colorant (B), a photopolymerizable compound (C), a photopolymerization initiator (D) and a solvent (E), which are generally used in the related art for coloring photosensitive resin combinations. thing. In addition, any additional components generally used in the related field, such as additives, may also be contained.

[0036]

[0037] The alkali-soluble resin of the present invention has reactivity to light or heat and alkali solubility, and serves as a dispersion solvent for the respective components in the composition of the present invention.

[0038] The colored photosensitive resin composition of the present invention contains an alkali-soluble resin containing maleimide-based repeating units. The alkali-soluble resin has a glass transition temperature of 100 to 200°C. ...

Synthetic example 1

[0179]

[0180] 120 parts by weight of propylene glycol monomethyl ether acetate, 80 parts by weight of propylene glycol monomethyl ether, 2 parts by weight of Azobisisobutyronitrile, 13.0 parts by weight of acrylic acid, 45.0 parts by weight of N-benzylmaleimide, 15 parts by weight of phenylmaleimide, 27 parts by weight of methyl methacrylate and 3 parts by weight of n-dodecyl mercapto, and the air in the flask was exchanged with nitrogen. Then, a reaction was performed for 8 hours while the temperature was raised to 80° C. and stirred.

[0181] The synthesized alkali-soluble resin had an acid value of 101.5 mg KOH / g (solid content), and a weight average molecular weight of 12350 as measured by gel permeation chromatography (GPC) based on polystyrene.

Synthetic example 2

[0182]

[0183] The synthesis of alkali-soluble resin is synthesized according to the same procedure as described in Synthesis Example 1, just using 10.0 parts by weight of acrylic acid, 30.0 parts by weight of N-benzylmaleimide, 30 parts by weight of phenylmaleimide and 30 parts by weight of methyl methacrylate instead of 13.0 parts by weight of acrylic acid, 45.0 parts by weight of N-benzylmaleimide, 15 parts by weight of phenylmaleimide and 27 parts by weight of methacrylic acid methyl ester.

[0184] The synthesized alkali-soluble resin had an acid value of 78.9 mg KOH / g (solid content), and a weight average molecular weight of 13800 as measured by GPC in terms of polystyrene.

Abstract

The present invention relates to a colored photosensitive resin composition. More particularly, the present invention relates to a colored photosensitive resin composition comprising a maleimide-based repeat unit. By comprising an alkaline soluble resin having a glass transition temperature of 100-200C, the colored photosensitive resin composition has excellent developing velocity, adhesion properties, and sensitivity, and suppresses blooming phenomenon under the condition of a high temperature.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition and a color filter manufactured therefrom, and more particularly, relates to a color filter that does not cause pattern delamination during the developing process and has excellent sensitivity due to a high developing rate and excellent adhesiveness. A colored photosensitive resin composition capable of reducing blooming even under high temperature conditions, and a color filter manufactured therefrom. Background technique [0002] Recently, a liquid crystal display (LCD) device has attracted attention as a next-generation display device, which has reduced power consumption, is good in portability, has higher added value, and is technology-intensive. [0003] Among such liquid crystal display devices, an active matrix type liquid crystal display device including a thin film transistor that is A switching device capable of controlling ON / OFF of the voltage of each pixel. [00...
