<p>PURPOSE:To obtain a photosetting resin compsn. excellent in water developability, that is, easy to develop with water and to obtain a photosetting resin compsn. excellent in heat resistance and adhesive property after setting, ensuring satisfactory sensitivity of a resist material to light, giving a clear image and excellent also in shelf stability. CONSTITUTION:This photosetting resin compsn. contains 100 pts.wt. polymer obtd. by copolymerizing 5-70wt.% monomer having an epoxy group with 30-80wt.% monomer having a tert. nitrogen atom and 0.01-20 pts.wt. optical proton generating agent. The polymer may be obtd. by copolymerizing the monomers with other monomer copolymerizable with the monomers. This resin compsn. is blended with a reactive diluent so as to regulate the viscosity.</p> |
