PURPOSE:A coating composition having a flatting effect and excellent storage stability and providing moldings excellent in abrasion and scratch resistance, consisting mainly of a particulate crosslinked emulsion polymer and a specified polyfunctional acrylate. CONSTITUTION:An actinic ray-curable coating composition prepared by mixing 100pts.wt. monomer mixture comprising at least 30% compound containing at least three (meth)acryloyloxy groups and at most 70% compound containing one or two alpha,beta-ethylenically unsaturated bonds (hereinafter, referred to simply as ''bond'') with 0.01-6.0pts.wt. photosensitizer, and 0.5-30pts.wt. multistage emulsion crosslinked (co)polymer comprising an inner layer comprising a crosslinked emulsion (co)polymer comprising 75-99% reactive monomer containing one ''bond'' and 1-25% reactive monomer containing at least two ''bonds'' and a copolymer comprising 85-99.9% reactive monomer containing one ''bond'' and 0.1-15% graft-crosslinking agent containing at least two ''bonds'' and the outermost layer comprising a crosslinked copolymer comprising 75-99% reactive monomer containing one ''bond'' and 1-25% reactive monomer containing at least two ''bonds''. |
