Zusammenfassung:	PURPOSE:To obtain a urethane resin composition which can show excellent adhesion to and close contact with any of plastics including polar and nonpolar polymer materials at ordinary temperatures. CONSTITUTION:This composition comprises a polyisocyanate and a urethane resin made from a mixed polyol comprising 100 pts.wt. polyether polyol, 5-100 pts.wt. polyester type rosin polyol and 5-100 pts.wt. hydroxyl-terminated polybutadiene having a molecular structure in which the 1,2-addition molecules prevail.
