PURPOSE:To provide the titled ink compsn. excellent in adhesiveness, resistance to heat of soldering, solvent, etc., by adding a specified isocyanurate as a photopolymerizable monomer. CONSTITUTION:The ink compsn. consists of (A) a photopolymerizable prepolymer[e.g., di(meth)acrylate of alkylene oxide adduct of bisphenol A], (B) a photopolymerizable monomer, (C) a photosensitizer (e.g., benzoin methyl ether) and (D) an extender (e.g., calcium carbonate or clay), and a mixture. of about 100-10wt% tris(meth)acryloyloxyalkyl isocyanurate and about 0-90wt% hydroxyalkyl acrylate is used as component B. |
