(57) [Problem] To provide an aqueous resin dispersion which can be used as an adhesive for polyolefin having excellent adhesive strength. An aqueous resin dispersion comprises an olefin block copolymer (A) represented by the following general formula (I) or a thermoplastic resin (B) other than the (A). PO-fR (I) wherein PO is a repeating unit derived from an olefin having 2 to 20 carbon atoms and has a weight average molecular weight Is a 2,000 or more polyolefin segment, f is an ether bond, an ester bond or an amide bond, R is a functional segment obtained by a chain polymerization reaction and containing a repeating unit having a weight average molecular weight of 500 or more.) |
