PROBLEM TO BE SOLVED: To provide an aqueous polyurethane resin having the flexibility which aqueous polyurethane resins inherently possess, and excellent adhesion and blocking resistance to plastics such as nylons and polyesters. SOLUTION: The aqueous polyurethane which is used can be obtained by reacting a high molecular weight polyol, a hydride of a petroleum resin having active hydrogens, and a polyisocyanate compound as the major components. |
