Embodiment 1

[0177] Among the components described in the following Table 1, the total amount of the pigment that is the precolor material (D) and the pigment dispersant that is the additive (F) becomes 20% by mass was mixed, and the pigment was sufficiently dispersed using a bead mill, then the beads were separated, and the remaining component including propylene glycol monomethyl ether acetate was added and mixed to obtain a colored photosensitive resin composition.

[0178] Table 1

[0179] Coloring material (D)

[0180] A 2-inch square glass substrate (manufactured by Corning, #1737) was washed sequentially with a neutral detergent, water, and alcohol, followed by drying. Make 100mJ / cm 2 The exposure amount (365nm) was exposed, and the film thickness after drying was 1.9 μm after omitting the thickness during the development process. The above-mentioned colored photosensitive resin composition was coated on the glass substrate, and then, in a clean oven, the 100°C for 3 min...

Embodiment 2

[0182] In Example 1, except having changed Irgacure-369 into the following oxime type initiator, the same operation as Example 1 was performed, and the evaluation result is shown in Table 2.

Abstract

A stained sensitization resin comprising a binder resin, a photo-polymerization compound, a photo-polymerization inducer, a stained material and a solvent, is provided. The binder resin (A), which contains unsaturated function group, is made from the copolymerization of (A1)~(A3) and then reacts with (A4). The photo-polymerization inducer (C) is the at least one compound selected from the combination of triazine compound, acetophenone compound, biimidazole compound and oxime compound. (A1): a compound, which in one of its molecule contains at least one skeleton selected from the combination of the tricyclodecane skeleton and the dicyclopentadiene skeleton, and unsaturated bonds; (A2): compound, which contains the unsaturated bonds of (A1) and (A3) for polymerization; (A3): unsaturated carbonic acid; (A4): compound, which in one of its molecule contains the unsaturated bond and epoxy group.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition. Background technique [0002] Usually utilize spin coater on the substrate that forms black matrix pattern, after coating the coloring photosensitive resin composition that contains the pigment of each color corresponding to red, green and blue evenly, carry out heating and drying (hereinafter referred to as pre-drying) ), to expose and develop the coating film, and then heat and cure (hereinafter, often referred to as post-drying) as needed. The above operations are repeated for each color, and the color liquid crystal is manufactured by forming pixels of each color. Color filters used in monitors, imaging devices, etc. For such a colored photosensitive resin composition, an acrylic resin having a carboxyl group in a side chain is used because it is excellent in light resistance and has little color change. For example, a photosensitive resin composition (Specific KOKAI Pu...
