Abstract:
1. A water-based composition comprising (A) an aqueous dispersion of modified polyolefin, which is prepared by dispersing a modified polyolefin (a) in an aqueous medium, the polyolefin (a) being produced by modifying an unsaturated carboxylic acid- or acid anhydride-modified polyolefin (i) having a melting point not higher than 120° C. and a weight-average molecular weight within a range of 30,000-200,000, further with a compound (ii) having hydroxyl group at its one terminus and polyoxyalkylene chain; (B) at least one kind of aqueous resin selected from the group consisting of aqueous urethane resin, aqueous acrylic resin and aqueous polyester resin; and (C) pigment; the solid weight ratio of the component (A)/component (B) being within a range of 20/80-85/15, and containing the component (C) in an amount within a range of 0.5-200 parts by weight per 100 parts by weight of the total solid resin content of the composition.
