Abstract
Abstract A paint comprises a silyl group-containing vinyl resin having a main chain composed substantially of a vinyl polymer. The resin has at least one silyl group bonded to a hydrolyzable group, and contains 0.1 to 20% by weight of maleic anhydride by copolymerization. The resin has a molecular weight of 300 to 30,000. A method of manufacturing such a resin is also disciosed.
