ALKALI-SOLUBLE RESIN, PHOTOSENSITIVE RESIN COMPOSITION, AND PHOTOSENSITIVE CURED FILM

WIPO Patent Application WO/2024/082896

A1

An alkali-soluble resin, a photosensitive resin composition, and a photosensitive cured film. The alkali-soluble resin has a structure represented by general formula (1), wherein Ar1 represents a dianhydride residue; R1 represents H or an organic group having 1-10 C atoms; m is an integer of 10-10000, and r is an integer of 0-2; Ar2 represents a diamine residue, the diamine residue comprises at least two structural units, and one structural unit is as represented by general formula (2); and Ar1 and Ar2 contain at least one phenolic hydroxyl group. The structural unit represented by general formula (2) is introduced into the alkali-soluble resin structure, and comprises a siloxane structure, an aromatic structure and/or a fluorine-containing substituent structure, so that when the structural unit is applied to a photosensitive resin composition to form a cured film, good adhesion with a substrate is achieved, good transparency is achieved, and good heat resistance and low-temperature curing characteristics after curing are guaranteed.
