The present invention provides an aqueous adhesive composition including a resinous
phase dispersed in an aqueous medium, the resinous phase containing (a) a polychloroprene,
(b) optionally, a halogenated polyolefin different from (a), and (c) optionally,
an aminoplast resin. Further provided is an aqueous adhesive composition of a resinous
phase dispersed in an aqueous medium wherein the resinous phase includes (a) a
polychloroprene, (b) a halogenated polyolefin different from (a), and (c) a polyurethane
polymer having ionic salt groups. A multi-layer composite and methods for adhering
a thermoplastic material to a rigid substrate using the aqueous adhesive compositions
also are provided.
