PROBLEM TO BE SOLVED: To obtain a urethane resin-based contact adhesive which has a short time before tack development, high bond strength immediately after tack, a long tack range and a long pot life of lamination. SOLUTION: The urethane resin-based contact adhesive comprises a urethane- based resin (A) as a component obtained by reacting a urethane prepolymer having a main chain with a polyoxyalkylene polymer skeleton containing at least a polyoxyethylene with an alkyl group-substituted aminopropylalkoxysilane. The adhesive has improved tack and a long tack range by combining the urethane-based resin with a vinyl polymer (B). COPYRIGHT: (C)2004,JPO
