Aqueous photosensitive resin compsition and print obtained by using the same

摘要

An aqueous-based photosensitive resin for the production of printed circuit boards comprises (a) a carboxyl group-containing resin, (b) an amino compound; (c) a photo-curable unsaturated compound and (d) a photo-polymerization initiator. Component (a) may be an acrylic resin or an acid anhydride copolymer, e.g. a styrene-maleic anhydride copolymer, wherein the anhydride groups have been ring-opened with an alcohol or a primary or secondary amino which may have a polymerizable unsaturated bond. Component (c) may be replaced by an amino compound and/or a carboxyl group-containing resin which has a photopolymerizable unsaturated bond.
