PURPOSE: A photocurable coating or adhesive composition is provided to have high adhesion with aluminum, thereby capable of coating aluminum surface without specific pre-treatment, to have excellent abrasion resistance and yellowing resistance, weatherability, etc, and to be easily coated by a spray method. CONSTITUTION: A photocurable coating or adhesive composition comprises 10-100 parts by weight of methylmethacrylate monomer, 10-100 parts by weight of vinylphosphonic acid, 0.1-10 parts by weight of gamma-glycidoxypropyltrimethoxysilane, and 0.1-10 parts by weight of a photocuring agent. The equivalent of the epoxy resin is 150-250, and the viscosity is 2,000-5,000 cps. The methylmethacrylate monomer is one or more selected from a group consisting of 2-hydroxyethylacrylate and 1,6-hexanedioldiacrylate. |
