Abstract
An alkali developable photosensitive resin composition contains (J) a photopolymerizable unsaturated compound having a structure resulting from the addition reaction of (B) a compound having a β-diketone moiety or a compound having a β-ketoester group to the (meth)acryloyl group of (A) a compound having at least two (meth)acryloyl groups and a hydroxyl group and subsequent esterification of the hydroxyl group of the resulting addition product with (C) a polybasic acid anhydride. The compound having a β-diketone moiety is preferably a novel β-diketone compound represented by general formula (I): wherein Ris a C1-C20 alkyl group; Rrepresents R, OR, COR, SR, CONRR, or CN; R, R, and Rare each hydrogen, a C1-C20 alkyl group, etc.; a is 0 to 3; and b is 0 to 4.
