Problems solved by technology

[0004] However, as electronic devices such as displays continue to pursue high color resolution and high contrast, this requires the particle size of pigment particles to be ground smaller and smaller. In order to maintain the stability of pigment dispersion, the amount of dispersing aids is also increasing. This will cause several problems such as developing difficulties
In addition, in the development process, the tiny pigment particles dispersed in the alkali-soluble resin are more likely to be lost due to the scouring of the developer, and the chemical resistance is poor, resulting in unstable colors
[0005] In addition, the manufacturing process of the color filter requires multiple heat treatment steps, and the steps are generally required to be completed at a high temperature above 200°C, but if the conventional photosensitive resin composition is heated at 200°C for 1 hour If left or right, there will be problems such as aggregation of pigment particles and poor heat resistance.

Abstract

The invention relates to an alkali-soluble bonding resin polymer. The alkali-soluble resin used as part of the photosensitive material for manufacturing color filters can improve the disperse storage stability, photosensitivity, development performance and adhesiveness of the photosensitive resin composition and reduce the changes of the chromaticity coordinate. The alkali-soluble resin is prepared by copolymerizing unsaturated monomers disclosed as Formula (1) with unsaturated monomers containing at least one carboxylic group or acid anhydride group and (or) other polymerizable unsaturated monomers.

Description

technical field [0001] The invention relates to an alkali-soluble resin and a preparation method thereof. The alkali-soluble resin can be used in a photosensitive resin composition. When the photosensitive resin composition based on the alkali-soluble resin of the present invention is used as a photosensitive material for manufacturing a color filter, it has a Stability, high sensitivity, excellent developability, heat resistance, chemical resistance, etc. Background technique [0002] The color filter is a key device for liquid crystal display to realize color display, and the performance of the color photoresist layer, which is the most important part of the color filter structure, directly affects the display effect of the liquid crystal display. With the increasing market demand for office equipment such as color liquid crystal displays and camera filters, the production technology of color filters is also tending to be diversified. For example, dyeing method, printing ...
