One component room temperature setting composition

Claim 1

A one component room temperature setting composition which comprises: (A) a vinyl polymer having on the polymer chain end or the side chain thereof at least one silyl group having a hydrolyzable group per one polymer molecule, the main chain of the vinyl polymer consisting essentially of a polymer of a vinyl compound; the silyl group-containing vinyl polymer (A) having a number average molecular weight of 1,000 to 10,000 and containing as a comonomer, 0.1 to 10% by weight of units of a vinyl compound having active hydrogen in the form of a group selected from the group consisting of a carboxyl group, an hydroxyl group, an amino group and an acid amido group, (B) 0.005 to 10 parts of a hardener, (C) 0 to 200 parts of a pigment, (D) 0.1 to 100 parts of at least one member selected from the group consisting of a hydrolyzable silicon compound of the general formula: X.sub.4-n.sup.1 --Si--R.sub.n.sup.2 wherein R 2 is an organic group bonded to the silicon atom through a carbon atom, X 1 is a hydrolyzable group selected from the group consisting of an alkoxyl group, an alkoxy-alkoxyl group, a phenoxy group, an acyloxyl group, a ketoxymate group, an amino group, an aminoxy group, an acid amide group and an alkenyloxy group, and n is 0 or an integer of 1 to 3, and a partial hydrolysis product of the hydrolyzable silicon compound, and (E) 0 to 500 parts of a solvent, said parts being parts by weight per 100 parts by weight of the component (A).
