ABSTRACT:
Disclosed is a coating composition comprising
(A) 5 to 60 parts by weight, on a solid basis, of colloidal silica,
(B) 5 to 70 parts by weight of a hydrolyzate and/or hydrolyzed and partially condensed product of a compound of the general formula ##STR1## (C) 10 to 80 parts by weight of a polyfunctional monomer containing a monomer of the general formula ##STR2## and (D) 0.01 to 5 parts by weight of a photopolymerization initiator containing a compound of the general formula ##STR3## provided that the combined amount of components (A), (B), (C) and (D) is 100 parts by weight.
This coating composition can be cured in air by exposure to ultraviolet light, and the resulting cured film is excellent in various properties (such as abrasion resistance) and adhesion to the substrate.
