PURPOSE:To prevent damage to the cloth, minimize bag capacity deterioration under high and low temperature, eliminate wear, peeling of coating and the like when an air bag is unfolded by coating a part of the bag body cloth with a polycarbonate type polyurethane resin. CONSTITUTION:A polycarbonate type polyurethane resin is a compound obtained a through a polymerization reaction of a polycarbonate diol, and a polyisocyanate. The said resin can be used in a condition such as an organic solvent solution, moisture dispersive solution, water suspension liquid of DMF, DMS and the like, and the resin coating can be used in a method such as coating, laminating, printing and spraying. A cloth made in such manner is cut to a suitable size, attached with a reinforcement cloth, straps, heat and gas sheltering material and the like and finished to a bag of specified shape.
