POSITIVE TYPE PHOTOSENSITIVE ANIONIC ELECTRODEPOSITION COATING COMPOUND RESIN COMPOSITION, ELECTRDEPOSITION COATING BATH USING THE SAME COMPOSITION, ELECTRODEPOSITION COATING AND PRODUCTION OF PRINTED CIRCUIT BOARD

摘要

PURPOSE:To obtain a positive type photosensitive anionic electrodeposition coating compound resin composition having high sensitivity, high resolving power and excellent water dispersion stability of electrodeposition coating bath. CONSTITUTION:A positive type photosensitive anionic electrodeposition coating compound resin composition comprising (A) an acrylic copolymer obtained by copolymerizing (a) acrylic acid and/or methacrylic acid with (b) a compound containing a group unstable to acid and (c) a polymerizable monomer to provide a homopolymer having =0 deg.C glass transition temperature as essential components and (B) a compound generating an acid by irradiation with active rays. An electrodeposition coating bath, a method for electrodeposition coating and production of printed circuit board using the same composition.
