Synthetic example 1

[0042] Into a 200mL flask, add 10g of monomer M-5400 (Toagosei Co., Ltd.), 20g of monomer M-5700 (Toagosei Co., Ltd.), 35g of benzyl methacrylate, 20g of N-phenylmaleimide, and part of propylene glycol Monomethyl ether acetate, molecular weight regulator (dodecyl mercaptan), under the protection of nitrogen, the system is heated to a predetermined temperature, and under stirring, the azobisisobutyronitrile is dissolved in a constant pressure dropping funnel. The remaining propylene glycol methyl ether acetate solution and 15 g of methacrylic acid were added dropwise into a three-necked flask within 30 minutes, then stirred and reacted at a constant temperature for 3 hours, the temperature was lowered to room temperature, and the solvent was removed to obtain alkali-soluble resins B1-B4 respectively. The weight-average molecular weight and molecular weight distribution of the polymer were measured by GPC, and the acid value was determined by acid-base titration.

Abstract

The invention belongs to the field of liquid crystal displays, and particularly relates to an alkali-soluble resin polymer for a color light filter and a light-sensitive resin composition. The alkali-soluble resin polymer disclosed by the invention is manly obtained by polymerization of 1,2-phthalic acid mono [2-[(1-oxo-2-allyl)oxygen]ethyl] ester, an unsaturated carboxylic acid or anhydride monomer (b1), an unsaturated carboxylic acid or anhydride monomer (b1) containing hydroxyl, an N-maleimide monomer (b3) and an unsaturated polymeric monomer (b4). According to the alkali-soluble resin polymer provided by the invention, the 1,2-phthalic acid mono [2-[(1-oxo-2-allyl)oxygen]ethyl] ester is selected and added; compared with the polymerized alkali-soluble resin polymer free of the monomer in the prior art, the alkali-soluble resin polymer has the advantages of relatively good storage stability, developing property, solvent resistance, and good matching property with a coloring agent, has low acid value, but has good developing property.

Description

technical field [0001] The invention belongs to the field of liquid crystal displays, and in particular relates to an alkali-soluble resin polymer and a photosensitive resin composition for a color filter. Background technique [0002] In the field of liquid crystal display (LCD), generally, the photosensitive resin composition is coated on the substrate and dried (pre-baked), exposed to ultraviolet rays through a photomask, hardened, and then developed by an alkaline developer to form a pattern. , and finally heat-treated (post-baked). Specifically, hardened films such as red, blue, and green pixels in color filters, resin light-shielding layers, protective films, or interlayer insulating films are all completed using this process. [0003] The color filter is a key device for liquid crystal display to achieve colorization, and the performance of the color photoresist used to prepare the color filter directly affects the display effect of the liquid crystal display. With ...
