<p>PURPOSE: To attain excellent curing property, durability and appearance by incorporating a specific quantity of an acrylic monomer, a photoinitiator, an epoxy-acrylate oligomer, an epoxy resin, an acidic curing agent for the epoxy resin and a cross-linking agent. CONSTITUTION: This photo-image forming composition contains about 15-35wt.% polymerizable acrylic monomer, about 3-15wt.% photosensitive free radical generating initiator capable of starting the polymerization of the acrylic component, about 5-35wt.% epoxy-acrylate oligomer, about 20-80wt.% curing epoxy resin composition for curing the composition, 0.1-10wt.% acidic curing agent for the epoxy resin and about 15wt.% hydroxyl group-reactive cross-linking agent. The components are selected so as to be dissolved in an alkali aq. solution, dried into a homogeneous composition, to form a homogeneous solution in an organic solvent and to be mutually compatible. As a result, excellent curing property, durability and appearance are attained.</p> |
