ABSTRACT OF THE DISCLOSURE A coating composition for the preparation of synthetic resin shaped articles excellent in abrasion resistance and (a) a polyfunctional monomer composition comprising (i) 40 - 100 wt.% of a polyfunctional monomer containing at least three methacryloyloxy or acryloyloxy groups in the molecule and having a MW of not higher than about 900 and (ii) 0 - 60 wt. % of a mono- or bi-functional monomer having one or two methacryloyloxy or acryloyloxy groups in the molecule and having a MW of not higher than about 300 per methacryloyloxy or acryloyloxy group, (b) 5 - 35 parts by wt., based on 100 wt. parts of the monomer composition, of at least one ultraviolet absorber, (c) 0.5 - 8 wt. parts, based on 100 parts by wt. of the monomer composition, of at least one polymeric material selected from polymers of alkyl methacrylates and alkyl acrylates, and (d) 0.01 - 6 parts by wt., based on 100 parts by wt. of the monomer composition, of a photo- sensitizer. The coating composition is coated on a synthetic resin shaped article and then, irradiated with ultraviolet rays in an inert gas or air to form a cross- linked coating film having a thickness of 1 to 30 microns.
