Zusammenfassung:PURPOSE:To obtain the title compsn. which gives a coating film excellent in weatherability and stain resistance by mixing a copolymer having specific alkoxysilyl groups and alcoholic hydroxyl groups with a specific silicon compd. and a cure catalyst. CONSTITUTION:This compsn. is prepd, by mixing 100 pts.wt. acrylic copolymer having a alkoxysilyl groups of formula I (wherein R is H or a 1-10C alkyl; R is H, a 1-10C alkyl, an aryl, or an aralkyl; and (a) is an integer of 0-2), 2-70 pts.wt. silicon compd. of formula II (wherein R is a 1-10C alkyl, an aryl, or an aralkyl; R is a 1-10C alkyl, an aryl, an aralkyl, or an alkoxy; and b is 0 or 1) and/or its deriv., and 0.1-20 pts.wt. cure catalyst (e.g. a combination of an org. carboxylic acid and an org. amine).
