PURPOSE:To provide a photocurable ink compsn. which is a solventless type and has excellent resistance to heat and chemicals, adhesion and electrical properties, consisting of two specified kinds of(meth)acryloylated resins and a photopolymerizable monomer in a specified ratio. CONSTITUTION:An ink compsn. contains at least one member (A) selected from acryloylated or methacryloylated bismaleimide/triazine resin and/or acryloylated or methacryloylated tris(2-hydroxy-ethyl) isocyanurate, at least one member (B) selected from acryloylated or methacryloylated bisphenol A type epoxy resin, novolak type epoxy resin, urethane resin, polyester resin and polybutadiene resin, and a photopolymerizable monomer (C) in a weight ratio of A:B=5:95-95:5 and (A+B):C=10:90-70:30 as main components. |
