Abstract:
1. An alkali developable photosensitive resin composition, comprising a photopolymerizable unsaturated compound having a structure resulting from: an addition reaction of a compound having a β-diketone moiety or a compound having a β-ketoester group, to a (meth)acryloyl group of 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 a polybasic acid anhydride, wherein the compound having a β-diketone moiety is represented by general formula (I): R R R R methylene units of an alkylene moiety of the substituents represented by R an alkyl moiety of the substituents represented by R an alkyl terminal of the substituents represented by R R R R a represents an integer of 0 to 3; b represents an integer of 0 to 4; when a or b is 2 or greater, then R the β-diketone moiety may have either a keto-form or an enol-form.
