A tintable coating composition is provided. It includes (A)(1) hydrolysates of silane compounds containing at least one epoxy group and not less than two alkoxy groups which are directly bonded to Si atom in the molecule, and, if necessary, (2) compounds containing silanol and/or siloxane groups in the molecule, and/or epoxy compounds; (B) fine silica particles having an average diameter of from about 1 to about 100 m mu ; and (C) an aluminum chelate compound having the general formula AlXnY3-n, where X is OL (and L represents a lower alkyl group), Y represents one or more ligands produced from a compound selected from the group consisting of M1COCH2COM2 and M3COCH2COOM4 where all of M1, M2, M3 and M4 are lower alkyl groups, and wherein n is an integer comprising 0, 1 or 2. This invention also concerns an article, preferably plastic, coated with said coating composition and having a hard and tintable, scratch-resistant film, which is formed by heating and curing. |
