PHOTOSENSITIVE RESIN COMPOSITION

摘要

PURPOSE:To provide an aq. emulsion type photosensitive resin compsn. excellent in water resistance, solvent, resistance and sensitivity. CONSTITUTION:This photosensitive resin compsn. contains an aq. emulsion of internally crosslinked acrylic resin obtd. by emulsion-polymerizing an acrylic monomer and a monomer having two or more polymerizable unsatd. groups in the presence of a photosensitive saponified vinyl acetate polymer having constituent units represented by the general formula, wherein R<1> is a quaternized arom. nitrogen-contg. heterocyclic residue, R<2> is H or lower alkoxy, (m) is 0 or 1 and (n) is an integer of 1-6.
