PURPOSE:To make a drying stage unnecessary by incorporating a specified polyvinyl alcohol copolymer, a polymerizable monomer having at least two free hydroxyl groups and a photopolymn. initiator. CONSTITUTION:This photosensitive resin compsn. contains a water soluble or water dispersible polyvinyl alcohol copolymer having 50-70mol.% degree of saponification of vinyl ester units and 60-130 deg.C heat melting and flowing start temp., a polymerizable monomer having a compd. represented by formula I and at least two free hydroxyl groups and a photopolymn. initiator. The polyvinyl alcohol copolymer is obtd. by saponifying a copolymer consisting of 0.1-20mol.% in total of 0.1-20mol.% nonionic monomer radical- copolymerizable with vinyl ester and 0-10mol.% monomer having an ionic hydrophilic group and the balance vinyl ester. When the photosensitive resin compsn. is used, a drying stage is made unnecessary. |
