Patent ID: 8158727

Claim:
An aqueous resin dispersion having dispersed in water a polymer (C) having a hydrophilic polymer (B) bonded to a polyolefin (A) in a ratio of (A):(B)=100:5 to 100:500 (weight ratio), wherein the polymer (C) is a graft copolymer having the hydrophilic polymer (B) graft-bonded to the polyolefin (A), the polyolefin (A) is a stereo-block polypropylene polymer having isotactic blocks and atactic blocks and having a propylene content of at least 50 mol%, and/or a propylene-butene copolymer having a butene content of from 15 to 50 mol%, which copolymer may include ethylene in an amount of at most 5 mol%, and the hydrophilic polymer (B) is a polyether resin.
