ABSTRACT:
An active energy ray-curing abrasion resistant coating composition is provided by incorporating following components: (a) a carboxylate-containing polyfunctional acrylate obtained by reacting a tetracarboxylic dianhydride and a hydroxyl group-containing polyfunctional acrylate having hydroxyl group(s) and at least three acryloyl groups and then neutralizing the reaction product; (b) a polyfunctional acrylate having at least three acryloyl groups; (c) an organic solvent; and (d) a photopolymerization initiator. The composition may comprise in addition to the components (e) a silica sol in an organic solvent as a dispersion medium. The composition may further comprise in addition to the components (f) an acrylic resin. Such composition is an active energy ray-curing abrasion-resistant coating composition which forms a film having excellent adhesion to a plastic sustrate, transparency, abrasion resistance and antistatic properties.
