Patent ID: 8877427

Claim:
A photosensitive resin composition, comprising: component (A), and one or both of component (B) and component (C): wherein component (A) is a 1,4-dihydropyridine derivative represented by the following general formula (1): where R 1 represents an alkyl group having 1 to 3 carbon atoms; and R 2 and R 3 each represent a hydrogen atom or an alkyl group having 1 or 2 carbon atoms and may be identical to or different from each other; wherein component (B) is a combination comprising (x) and (y): wherein (x) is a carboxyl group-containing linear polymer having a carboxylic acid equivalent of 300 to 1,300; and wherein (y) is an epoxy resin having a molecular weight of 100 to 5,000; wherein component (C) is a linear polymer comprising a carboxyl group and an epoxy group, the linear polymer having a carboxylic acid equivalent of 300 to 1,300 and an epoxy equivalent of 200 to 1,300, wherein a content of component (A) is 0.1 to 20% by weight in the entire photosensitive resin composition, wherein, if component (B) is present in the composition: a content of (x) is 15 to 95% by weight in the entire photosensitive resin composition, and a content of (y) is 5 to 85% by weight in the entire photosensitive resin composition, and wherein, if component (C) is present in the composition, a content of component (C) is 40 to 99.9% by weight in the entire photosensitive resin composition.
