An adhesive without causing movement or peeling of the relief film and yet may facilitate the re-sticking thereto. A urethane prepolymer represented the formula [I]: A-O-CONH-B-NHCO--[O-CpHq-(O-CO-CrHs-CO-O-CpHq)l-O-CONH-B-NHCO} u-(O-D-O-CONH-B-NHCO)v--O-CpHq-(O-CO-CrHs-CO-O-C pHq)t-O-CONH-B-NHCO}u]w -O-Epolymerizes and cures to make adhesive polymer. The adhesive polymer is used for an adhesive material for fixing a relief film onto a printing base of a printing machine.
