Claim Text:
1. An aqueous adhesive composition, comprising: (A) an acid-modified polyolefin-based resin, (B) a core-shell hardener having a shell consisting of an acrylic copolymer having a glass transition temperature of −30° C. to 100° C. and a core consisting of an epoxy group-containing resin compound or a monomer thereof capable of cross-linking to the acid-modified polyolefin-based resin, and (C) an amine-based hardener having a melting point of 60° C. or higher, in an amount such that 0.005-1 equivalent groups are present based on 1 equivalent of carboxyl groups in the acid-modified polyolefin-based resin, and selected from at least one of the group consisting of 4,4′-diaminodiphenylmethane, 2,4′-diaminodiphenylmethane, 3,3′-diaminodiphenylmethane, 3,4′-diaminodiphenylmethane, 2,2′-diaminobiphenyl, 2,4′-diaminobiphenyl, 3,3′-diaminobiphenyl, 2,4-diaminophenol, 2,5-diaminophenol, o-phenylenediamine, m-phenylenediamine, 2,3-tolyenediamine, 2,4-tolylenediamine, 2,5-tolylenediamine, 2,6-tolylenediamine, 3,4-tolylenediamine, 1,12-dodecanediamine, 1,10-decanediamine, 1,8-octanediamine, 1,14-tetradecanediamine, 1,16-hexadecanediamine, dodecanediohydrazide, 1,3-bis(hydrazinocarboethyl)-5-isopropylhydantoin having melting point 121-123° C. of the formula a compound having melting point 174-181° C. of the formula and a compound having melting point 147-155° C. of the formula wherein the aqueous adhesive composition does not omit any solvent gas when applying or drying.
