PURPOSE: To obtain a photopolymerizable resin compsn. having sufficient resistance to a gold plating soln. by constituting the resin compsn. of each specified pts.wt. of a specified thermoplastic polymer to be used for binder, specified crosslinking monomer, and photopolymn. initiator. n CONSTITUTION: A photopolymerizable resin compsn. is constituted of 40-70pts.wt. thermoplastic polymer for binder obtd. by copolymerizing 3-30wt.% at least one kind among styrenic compd. expressed by the formula I and derivs. thereof substituted in the ring, with 15-45wt.% at least one kind of compd. selected from a group consisting of specified hydroxyalkyl acrylates, 25-60wt.% at least one kind of compd. selected from a group consisting of specified hydroxyalkyl methacrylates, and 15-35wt.% at least one kind of monomers having 3-15C α,β-unsatd. carboxyl groups; 25-50pts.wt. crosslinking monomer consisting of at least one kind of compd. having ≥one ethylenic unsatd. group in a molecule; and 0.1-10pts.wt. photopolymn. initiator. Thus, a photopolymerizable resin compsn. having sufficient resistance to a gold plating soln. is obtd. n COPYRIGHT: (C)1990,JPO&Japio |
