A PRINTING RELIEF AND AN ADHESIVE MATERIAL FOR MAKING THE SAME

摘要

Ae 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-C p H q-(O-CO-C r H s-CO-O-C p H q)t-O-CONH-B-NHCO}u-(O-D-O-CONH-B-NHCO )v- -{O-C p H q-(O-CO-C r H s-CO-O-C p H q)t-O-CONH-B-NHCO}u]w-O-E .....[I] polymerizes 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.
