POLYMERIZABLE UNSATURATED GROUP-CONTAINING ALKALI-SOLUBLE RESIN, PHOTOSENSITIVE RESIN COMPOSITION CONTAINING SAME AS ESSENTIAL COMPONENT, AND CURED PRODUCT THEREOF

WIPO Patent Application WO/2022/092281

A1

The present application provides a photosensitive resin composition that has high heat resistance and is capable of maintaining a rectangular cross-sectional shape and not exhibiting heat-sagging, and a cured product thereof. A polymerizable unsaturated group-containing alkali-soluble resin according to the present invention is represented by general formula (1) and has, in each molecule, a carboxy group and a polymerizable unsaturated group. (In formula (1), X1 represents a tetravalent aromatic ring-containing group, and Y1 represents a divalent aromatic ring-containing group. A portion of the hydrogen atoms in X1 and Y1 are optionally substituted with a linear or branched chain hydrocarbon group having 1-20 carbon atoms. V1 is a substituent represented by general formula (2). The value of l, as an average, is 0.2-4.0. Q1 is a hydrogen atom or a linear or branched chain hydrocarbon group having 1-20 carbon atoms.) (In formula (2), R1 represents a hydrogen atom or a methyl group. L represents a substituent represented by general formula (3). * represents a binding site with an oxygen atom (O) in formula (1).) (In formula (3), M represents a divalent or trivalent residue derived from a dicarboxylic acid, a tricarboxylic acid, or an acid monoanhydride of either, and p is 1 or 2. * represents a binding site with an oxygen atom (O) in formula (2).)
