PROBLEM TO BE SOLVED: To provide an adhesive compsn. enabling adhesion between a material of a low polarity, e.g. a polyolefin material, and other materials. SOLUTION: This compsn. comprises an aqueous resin dispersion obtained by polymerizing at least one kind of polymerizable unsaturated monomer contg. anα,β-ethylenically unsaturated bond, in the presence of an aqueous polyurethane resin dispersion obtained from a polyol, contg. a polyester polyol obtained by ring-opening addition polymerization of lactones to dimethylolbutanoic acid as an initiator, a polyisocyanate compd., and a chain extender.
