PURPOSE: A UV-curable paint composition with high hardness is provided to have excellent touch in the touch panel, the smart phone, the smart display, etc, of the method of electrostatic capacity, and to have super high hardness, and excellent adhesion, scratch resistance, and shock resistance, distortion performance, and light characteristic. CONSTITUTION: A UV-curable paint composition comprises: 10-40 weight% polyfunctional melamine-acrylate oligomer; 1-10 weight% oligomer in which the surface of a nanoalumina colloid compound is coat-treated by silicon; 0.5-5 weight% silane-boron coupling agent; 0.05-0.5 weight% rheological property enhancer; 0.5-5 weight% photocure initiator (photoinitiator); and a residue organic solvent. The polyfunctional melamine-acrylate oligomer is one among 3-6 functional groups. The silane-boron coupling agent is the mixture of a tetraethoxy boron compound and 3-methacryloxypropyltrimethoxysilane to the weight ratio of 1:1. |
