[0176] Preparation Example 1: Preparation of Alkali-soluble Resin

[0177] Add 200 parts by weight of propylene glycol monomethyl ether acetate, 45 parts by weight of propylene glycol monomethyl ether, 2 Azobisisobutyronitrile (AIBN), 15 parts by weight of acrylic acid, 70 parts by weight of benzyl methacrylate, 15 parts by weight of styrene and 3 parts by weight of n-dodecanethiol, then nitrogen replacement . After that, the temperature of the reaction solution was raised to 110° C. with stirring, and the reaction was continued for 8 hours to obtain an alkali-soluble resin. It was confirmed that the obtained alkali-soluble resin had a weight average molecular weight (Mw) of about 16000 and an acid value of 100.4 mg KOH / g by GPC measurement.

[0196] Color filters were prepared using the colored photosensitive resin compositions prepared in Examples and Comparative Examples.

[0197]Specifically, each colored photosensitive resin composition was coated on a glass substrate by spin coating, and the glass substrate was placed on a heating plate and maintained at a temperature of 100° C. for 3 minutes to form a thin film on the glass substrate. Subsequently, a test photomask (with a pattern exhibiting a stepped transmittance in the range of 1% to 100% and a line / space pattern of 1 μm to 50 μm) was placed on the film, and Use a 1KW high pressure mercury lamp at 100mJ / cm with an interval of 100μm 2 Under UV irradiation without any special filter, the mercury lamp includes all of the g-line, h-line and i-line. The ultraviolet irradiated film was immersed in an aqueous KOH solution (pH 10.5) used as a developing solution for 2 minutes. Af...

Abstract

The invention provides a colored photosensitive resin composition and a color filter comprising the same. The colored photosensitive resin composition uses a color filter which is formed by the composition and comprises a liquid crystal display device which has the color filter. The colored photosensitive resin composition includes a thermally induced photoacid generator, a coloring agent, an alkali-soluble resin, a photopolymerization initiator, a photopolymerization compound and a solution, wherein the thermally induced photoacid generator is a non-ion thermally induced photoacid generator which has a decomposition starting temperature of lower than 200 DEG C. According to the invention, on the basis of the colored photosensitive resin composition can be sufficiently cured even through a low-temperature burning so as to provide excellent adhesiveness and chemical resistance for the color filter which is formed by the composition.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition and a color filter including the colored photosensitive resin composition. Specifically, the present invention provides a colored photosensitive resin composition, a color filter formed using the composition, and a liquid crystal display device having the color filter, the colored photosensitive resin composition can be calcined at a low temperature lower than 200°C And is fully cured, thus showing good adhesion and chemical resistance;. Background technique [0002] Color filters have been widely used in imaging devices and liquid crystal displays (LCDs), and their applications are expanding. In the past, by uniformly coating a colored photosensitive resin composition including red, green or blue pigments on a substrate on which a black matrix pattern is formed, heating and drying (pre-baking), exposing and developing the resulting coating film Instead, a color filter is pre...
