Abstract:
1. A positive photosensitive resin composition comprising: a polyamide resin (A) including a repeating unit represented by the following formula (1), and a photosensitive agent (B) comprising an ester of at least one kind of phenolic compound selected from the group consisting of the following formulae (b-1) to (b-5) with at least one of 1,2-naphthoquinonediazide-4-sulfonic acid and 1,2-naphthoquinonediazide-5-sulfonic acid: wherein X is at least one kind of organic group selected from the group consisting of the following formulae (6-1) to (6-7) and Y is at least one kind of organic group selected from the group consisting of the following formulae (8-1) to (8-8); R 1 is a hydroxyl group, —O—R 3 , an alkyl group, an acyloxy group or a cycloalkyl group; R 2 is a hydroxyl group, a carboxyl group , —O—R 3 or —COO—R 3 ; h is an integer from 0 to 8; i is an integer from 0 to 8; R 3 is an organic group having 1 to 15 carbon atoms; when there are plurality of R 1 s, R 2 s or R 3 s, they may be the same or different from each other; when there is no hydroxyl group as R 1 , at least one R 2 has to be a carboxyl group; and when there is no carboxyl group as R 2 , at least one R 1 has to be a hydroxyl group, in the formulae, * means being connected to an NH group; A is —CH in the formulae, * means being connected to a C═O group; A is —CH wherein each of R 8 to R 11 is a methyl group or an ethyl group; and the R 8 s, R 9 s, R 10 s or R 11 s may be the same or different from each other.
