Patent ID: 7932012

Claim:
A photosensitive resin composition comprising: (A) a polymer having an acid functional group and/or a substituent derived therefrom; (B) a compound represented by the general formula (10): X—(NR 4 R 5 ) n (10) wherein X represents an n-valent organic group, n represents an integer of 2 to 6, and each of R 4 and R 5 represents hydrogen or a monovalent organic group, at least one of R 4 and R 5 is selected from the group consisting of: wherein R 3 represents a monovalent organic group; X 3 represents an oxygen, sulfur, or nitrogen atom; and n represents 1 when X 3 is an oxygen atom or a sulfur atom, or n represents 2 when X 3 is a nitrogen atom; (C) a photoreactive compound; and (D) a solvent, wherein said polymer (A) is a heat-resistant polymer, and wherein the heat-resistant polymer is a polyimide precursor represented by the general formula (1) below or polyimide derived from the precursor, a polybenzoxazole precursor represented by the general formula (2) below or polybenzoxazole derived from the precursor, a copolymer thereof, or a mixture thereof: wherein X 1 represents a tetravalent organic group, Y 1 represents a divalent organic group, R 1 represents hydrogen or a monovalent organic group, and n 1 represents an integer of 2 to 500 corresponding to the number of the repeating units of the polymer, wherein X 2 represents a divalent organic group, Y 2 represents a tetravalent organic group, of which two valences are used in bonding to hydroxyl groups, R 2 represents hydrogen or a monovalent organic group, and n 2 represents an integer of 2 to 500 corresponding to the number of the repeating units of the polymer.
