<p>Disclosed is an addition interpolymer (vinyl type) containing at least one silicon atom directly bonded to a hydrolyzable group in which the addition interpolymer is derived from a mixture of copolymerizable ethylenically unsaturated monomers containing an isobornyl group-containing monomer selected from the group consisting of isobornyl methacrylate, isobornyl acrylate and a mixture thereof. The amount of the isobornyl group-containing monomer ranges from 10 to 60 percent by weight based on the total weight of the mixture of copolymerizable ethylenically unsaturated monomers. Also disclosed is a method of coating a substrate comprising the steps of (a) forming a basecoat by coating the substrate with one or more applications of a pigmented basecoating composition; and (b) thereafter forming a topcoat by coating the basecoat with one or more applications of an essentially clear topcoating composition; wherein the basecoating composition and/or the topcoating composition comprises the aforesaid addition interpolymer.</p> |
