PURPOSE: An ultraviolet curing paints composition is provided that provides an excellent surface hardness, adhesion and scratch resistance of a coating film. CONSTITUTION: The composition comprises a copolymerizable multifunctional acrylic oligomer and monomer; a monofunctional epoxy acrylic monomer comprising a copolymerizable amine group; and a photopolymerizable initiator, wherein the composition ratio of the components is each 70 to 90 wt%: 10 to 30 wt% and 5 to 10 wt% based on total weight of the oligomer and monomer in the composition. The copolymerizable multifunctional acrylic oligomer and monomer is one or at least two mixture selected from the group consisting of polyol polyacrylate such as trimethyolpropane triacrylate, ditrimethyol propane tetraacrylate, pentaerythritol triacrylate and dipentaerythritol hexaacrylate, and urethane acrylate obtained by reacting a polyfunctional alcohol, a polyfunctional isocyanate and an acrylate containing a hydroxy group. |
