Embodiment 1

[0185] The components were mixed into the resin solution part (reduced solid content: 5.172 parts) containing (resin A-1) obtained in Synthesis Example 1 to obtain the compositions shown in Table 1, and a colored photosensitive resin composition was obtained. 1. The storage stability of colored photosensitive resin composition 1 was evaluated, and the results are shown in Table 2.

[0186]

[0187] The colored photosensitive resin composition was stored at 23°C and 40°C for 4 days, and the value obtained by dividing the viscosity of the colored photosensitive resin composition after storage by the viscosity of the composition before storage was expressed in %. Small changes in viscosity are preferred, eg, preferably 98 to 102% at 23°C

[0188] Viscosity: Measured at 23°C and 40°C using a viscosity (VISCOMETER TV-30; manufactured by Toki Sangyo Co., Ltd.).

[0189]

[0190] A 2 inch square glass plate <#1737 manufactured by Corning) was washed sequentially with a neutral ...

Embodiment 2

[0198] Colored photosensitive resin composition 2 was obtained in the same manner as in Example 1 to obtain the compositions shown in Table 1. Table 2 shows the results evaluated in the same manner as in Example 1.

Abstract

The present invention discloses a coloring photosensitive resin composition, which comprises substrate resin (A), coloring agent (B), photopolymerization compound (C), initiators for photopolymerization (D) and impregnant (E), wherein the substrate resin (A) comprises a structure unit obtaining from a monomer (A1) which is arranged with carbon-carbon double bonds and aliphatic polycyclic epoxides, and a structure unit obtaining at least from one monomer (A2) of unsaturated carboxylate and unsaturated carboxyl anhydride.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition. Background technique [0002] Pixels of color filters used in liquid crystal displays are formed using colored photosensitive resin compositions. [0003] The formation of the pixel is carried out as follows: On the substrate, a colored photosensitive resin composition containing any one of the three primary colors R, G and B is applied on the substrate using an application device, and the volatile components are removed by means such as heating. After that, the composition is exposed through a mask, and then, using a developer such as an alkaline aqueous solution or the like, the non-exposed part is developed in the case of a negative type, and the exposed part is developed in the case of a positive type, which is then removed to form a pattern, And the pattern obtained is subjected to heat treatment (hereinafter, sometimes referred to as post-baking) to form a pixel having ...
