Abstract
In a coated article comprising an undercoat and an overcoat on a substrate, the undercoat comprising a compound having a hydrolyzable group-bearing silyl group represented by SiX wherein X is a hydrolyzable group and “a” is equal to 0, 1 or 2; and the overcoat is based on a composition comprising a silicone resin-containing emulsion resulting from emulsion polymerization of a mixed solution containing (A-1) a silanol group-bearing silicone resin comprising 30-100 mol % of T units and based on the T units, 30-80 mol % of T-2 units, and having a Mn of at least 500, and (A-2) a radical-polymerizable vinyl monomer. Due to a firm bond between the overcoat and the undercoat, the coated article exhibits a weather and water resistance sufficient to withstand long-term outdoor exposure.
