PHOTOSENSITIVE RESIN, COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive resin composition affording a photosensitive layer with high sensitivity and further having excellent adhesiveness during developing and to provide a method for producing the composition.

SOLUTION: The alkali-soluble photosensitive resin is an α,β-unsaturated group-containing carboxylic acid compound prepared by adding a polybasic carboxylic acid anhydride to a polyhydric alcohol compound represented by general formula (1) and having the α,β-unsaturated groups. The acid value is 20-150 expressed in terms of solid content.
