PROBLEM TO BE SOLVED: To provide a two-pack aqueous adhesive for synthetic leather, which is excellent in oleic acid resistance, exhibits little change in the viscosity, has a relatively long pot life, and exhibits a good two-liquid compatibility. SOLUTION: The two-pack aqueous adhesive for synthetic leather comprising a base agent containing an aqueous polyurethane resin, and a curing agent containing a polyisocyanate compound having a biuret bond or modified with trimethylolpropane is prepared. The two-pack aqueous adhesive for synthetic leather is excellent in oleic acid resistance, exhibits little change in the viscosity, has a relatively long pot life, and exhibits a good two-liquid compatibility. Therefore, according to the two-pack aqueous adhesive for synthetic leather, a synthetic leather excellent in oleic acid resistance can be manufactured with good workability.
