Problems solved by technology

At the same time, in order to improve the developing efficiency of color filters, more high-viscosity alkali-soluble resins are often added to the formula of the raw material color photoresist, but this will lead to excessive viscosity of the system and limit the self-leveling of the photoresist. ability
If the content of alkali-soluble resin is reduced, although the viscosity of the system can be reduced and the leveling situation can be improved, there will be residual adverse phenomena

Abstract

The invention discloses an alkali soluble resin and its preparation method. The alkali soluble resin has a chemical structural formula shown in formula 1, wherein a is an integer ranging from 1 to 5, b is an integer ranging from 1 to 5, c is an integer ranging from 1 to 10, d is an integer ranging from 1 to 10, m is an integer ranging from 1 to 30, n is an integer ranging from 1 to 10, and R is hydrogen, alkyl, alkoxy or an acrylic group. The alkali soluble resin has a weight-average molecular weight of 3500-35000. The invention also discloses a photosensitive resin composition containing the alkali soluble resin, and a color photoresist glue that contains the photosensitive resin composition and is used for color filters, as well as a display device containing the color photoresist glue, which has the advantage of a level and smooth coating surface.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and in particular relates to an alkali-soluble resin, a photosensitive resin composition containing the alkali-soluble resin and applications thereof. Background technique [0002] The raw material for preparing the color filter of a liquid crystal display is a colored negative photoresist, which is coated on the surface of a glass substrate and then produced through a process of pre-baking-exposure-development-post-baking. [0003] One of the color negative photoresists is a color photoresist. In order to achieve higher resolution and more vivid color effects, the surface of the color photoresist is required to be dense and flat. However, during the production process, due to various reasons, surface defects such as orange peel, shrinkage cavity, and Bernard swirl will occur on the surface, resulting in uneven coating and seriously affecting the display effect. [0004] The general treatm...
