ABSTRACT:
An ultraviolet-curing covering composition comprising Component A which is obtained by reacting a hydroxyl group-containing polyfunctional acrylate with a silane coupling agent containing an isocyanate group(s), Component B of a polyfunctional acrylate having 3 or more acryloyl groups in the molecule, Component C of a silica sol in an organic solvent, and Component D of a photopolymerization initiator. This composition forms a coating film shows excellent hardwearing properties and adhesion to plastic substrates after ultraviolet-curing. Blending Component E of an acrylic resin and Component F of a solvent to the composition forms a coating film which can be processed before curing.
