Beschreibung
Zusammenfassung:	A two-pack aqueous adhesive, which comprises (A) an adhesive component comprising (a) a polycarbonate-urethane aqueous dispersion having a pH 5.0 - 8.5, which is prepared by self-emulsifying a carboxyl group-containing, hydroxy-terminated polyurethane polymer obtained from a polycarbonate diol, a carboxyl group-containing chain extender and a polyisocyanate compound in water in the presence of a tertiary amine, and (b) a conventional aqueous emulsion of a synthetic resin or a synthetic rubber, and (B) a curing component comprising a polyisocyanate compound, which can be cured even at a low temperature and is suitable for dry lamination of a proudct having complicated shape.
