Beschreibung
Zusammenfassung:	Disclosed are an aqueous adhesive composition for dry lamination and a laminate fabricated using the same. More particularly, the disclosed aqueous adhesive composition for dry lamination includes an aqueous resin dispersion A and a water-dispersible isocyanate B, wherein the aqueous resin dispersion A is prepared using the following ingredients (a) to (d), that is, an unsaturated monomer having a hydroxyl group (b), C1-C4 alkyl acrylic and/or methacrylic ester (c) and an additional unsaturated monomer (d) co-polymerizable with the unsaturated monomer (a), in the presence of an emulsifier having a phosphate group (a). The aqueous adhesive composition for dry lamination as described above exhibits excellent adhesion when used in laminate adhesion between at least two different plastic films, a plastic film and an aluminum foil or a metal welding film, etc., while having superior hydrothermal resistance sufficient for a resulting laminate to endure hot water conditions. This adhesive composition is a non-solvent adhesive and does not adversely influence the environment, while having excellent performance comparable to solvent type polyurethane. Moreover, the inventive composition has economic advantages.
