Abstract
A nonstaining coating composition which comprises as essential components (A) a specific aliphatic sulfonic acid compound or amine salt thereof, (B) a compound having per molecule at least one functional group selected among carboxyl, a carboxylic acid anhydride group, and a carboxyl group blocked with an alkyl vinyl ether, (C) a specific organosilicate and/or a condensate thereof, and (D) a resin having epoxy groups and/or alkoxysilyl groups in the molecule; and a method of finish coating. Also, a stain resistant coating composition which comprises (F') a specific modified resin and optionally (B) a compound having in the molecule at least one functional group selected from the group consisting of carboxyl group, carboxylic acid anhydride group and carboxyl group blocked with an alkylvinyl ether compound. They give a cured coating film which has nonstaining properties based on a high degree of hydrophilicity from immediately after the formation thereof and has satisfactory long-term weatherability, water resistance, and chemical resistance. The film can impart an excellent finish appearance to the article.
