Abstract:
1. An anionic-group-containing polymer represented by following Formula (2) having an alkoxysilyl group at its end, a salt thereof, or a hydrolyzed polymer being derived from the polymer or the salt thereof and comprising a hydrolyzed alkoxysilyl group: wherein W is a residue corresponding to a skeleton of an anionic-group-containing polymer; the nitrogen atom combined with W is a nitrogen atom derived from an isocyanate group at the end of the anionic-group-containing polymer; W has a structural unit represented by following Formula (2a): wherein Y is one of a residue derived from a compound (A1) containing no anionic group and having plural isocyanate-reactive groups and a residue derived from a compound (A2) having an anionic group and plural isocyanate-reactive groups; V combined with Y is a group derived from one of the isocyanate-reactive groups of the compound (A1) and the compound (A2), wherein both the residue derived from the compound (A1) and the residue derived from the compound (A2) as Y are contained in the polymer; Z is a residue derived from a polyisocyanate compound (A3), wherein a nitrogen atom combined with Z and a nitrogen atom on the opposite side to Z are nitrogen atoms derived from isocyanate groups of the polyisocyanate compound (A3); X is an alkoxysilyl-containing group represented by any one of following Formulae (2b), (2c), and (2d): wherein R wherein R wherein R n is an integer from 1 to 4.
