PHOTOSENSITIVE RESIN COMPOSITION, PHOTOSENSITIVE ELEMENT, METHOD FOR FORMING RESIST PATTERN, AND METHOD FOR MANUFACTURING PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive resin composition that is sufficiently effective to improve resolution and resist stripping characteristics.

SOLUTION: The photosensitive resin composition contains: (A) a binder polymer having a structural unit based on styrene or a styrene derivative, a structural unit based on a benzyl (meth)acrylate or a benzyl (meth)acrylate derivative, a structural unit based on a (meth)acrylic acid, and a structural unit based on an alkyl ester (meth)acrylate, and having a dispersion degree of 1.0 to 2.0; (B) a photopolymerizable compound; and (C) a photopolymerization initiator.
