Aqueous dry laminate adhesive composition for artificial leather and manufacturing method for artificial leather using the same

摘要

The present invention provides an adhesive composition which does not contain an organic solvent for use in a dry laminate process for manufacturing artificial leather. The dry laminate adhesive composition comprises (A) a water-borne polyurethane resin, (B) a cross linking agent, and (C) a thickener, wherein the water-borne polyurethane resin (A) has a softening temperature of less than 80° C. and a viscosity of the melt at 80° C. of less than 105 Pa.s, and wherein a softening temperature of a cured product obtained after curing a reaction product between the water-borne polyurethane resin (A) and the crosslinking agent (B) is higher than 120° C.
