Provided is an aqueous resin composition for polyolefin, which shows excellent adhesion to polyolefin and thus is useful for an aqueous coating agent for a polyolefin-based substrate, and has excellent stability. The aqueous resin composition for polyolefin is obtained by graft polymerization of 5-30 parts by weight of a chlorinated polypropylene resin having a chlorination degree of 10-40 wt% and 70-95 parts by weight of an acryl monomer. The aqueous resin composition has a hydroxyl value of 5-50 mg KOH/g, an acid value of 6.5-60 mg KOH/g, and a number average molecular weight of 60,000-150,000. The acryl monomer includes a carboxyl group-containing acryl monomer.
