PURPOSE:To obtain the titled ink having improved adhesivity to a substrate and free from from blotting of the ink, by compounding an epoxy resin with a specific compound, an acid anhydride and dicyandiamide, curing the composition with ultraviolet radiation and further curing with heat. CONSTITUTION:A composition composed mainly of (A) an epoxy resin, (B) a compound generating a Lewis acid by photo-decomposition (e.g. diazonium salt), (C) an acid anhydride (e.g. trimellitic anhydride) and (D) dicyandiamide is cured by ultraviolet radiation and then cured with heat (preferably at 100-200 deg.C for 1-60min) to obtain the objective ink. |
