摘要:
A coating composition for the preparation of synthetic resin shaped articles excellent in abrasion resistance and weatherability is described. This composition comprises (a) a polyfunctional monomer mixture comprising (i) 25-75 wt. % of at least one polyfunctional monomer of the formula (I): ##STR1## wherein at least three of X.sub.11, X.sub.12, X.sub.13, X.sub.22, X.sub.23 -X.sub.n2, X.sub.n3 and X.sub.14 are CH.sub.2 .dbd.CH.C00-- and the remaining groups are --OH, and n is an integer of 1-5, (ii) 25-75 wt. % of at least one polyfunctional monomer of the formula (II): ##STR2## wherein at least three of the R groups are CH.sub.2 .dbd.CH COO-- and each of the remaining is H or --OH, n.sub.1, n.sub.2, n.sub.3, n.sub.4, m.sub.1, m.sub.2, m.sub.3 and m.sub.4 are integers of 0, 1 or 2, and X is an integer of 1 to 10 and (iii) 0 to 50 wt. % of a monomer containing one acryloyloxy group and having a boiling point of at least 150.degree. C. at normal pressure and a viscosity of not higher than 20 cps/20.degree. C., and (b) 0.01-6.0 wt. parts, based on 100 wt. parts of the polyfunctional monomer mixture, of at least one photosensitizer. The coating composition is coated on a synthetic resin shaped article and then, irradiated with utraviolet rays in air to form a crosslinked coating film having a thickness of 1-30 microns.
