Problems solved by technology

However, when the composition is preserved, the composition becomes thick and gel appears in some cases, so according to the research of the present inventors, it has been found that a colored photosensitive resin composition containing a glycidyl group develops when preserved at 23°C. Insufficient storage stability

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 ...
