PHOTOSENSITIVE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a photosensitive resin compsn. usable as an aq. soln. and capable of forming a tough transparent hardened film by slight exposure and to obtain a colored photosensitive resin compsn. SOLUTION: This photosensitive resin compsn. consists of a water-soluble copolymerized resin obtd. by copolymerizing 2hydroxyethyl (meth)acrylate with methoxymethyl (meth)acrylamide and (meth)acrylamide and a water-soluble diazo resin and it is obtd. by carrying out the copolymn. in an aq. sol of tin oxide and mixing the resultant resin with the water-soluble diazo resin. This colored photosensitive resin compsn. consists of a water-soluble copolymerized resin obtd. by copolymerizing 2-hydroxyethyl (meth)acrylate with methoxymethyl (meth)acrylamide and (meth)acrylamide, a water-soluble diazo resin and a pigment and it is obtd. by carrying out the copolymn. in an aq. sol of tin oxide and mixing the resultant resin with the water-soluble diazo resin and the pigment.
