PHOTOSENSITIVE RESIN COMPOSITION, PHOTOSENSITIVE LAMINATE, FLEXIBLE CIRCUIT SUBSTRATE AND METHOD FOR FORMING PERMANENT PATTERN

摘要

A photosensitive resin composition comprising: (A) a binder resin which comprises an acid-modified resin having ethylenic unsaturated groups; (B) a radical-polymerizable compound; (C) a thermal crosslinking agent; and (D) a photopolymerization initiator. The acid-modified resin bears, at at least one end of the backbone chain, a structure having an ability to inhibit radical polymerization.
