SOLUTION: This tacky material of the printing machine has, on the surface, the tacky polymer obtained by impregnating an urethane prepolymer represented by the chemical formula into a support or applying the urethane prepolymer to the support and then polymerizing and curing the prepolymer. The tacky material is used for attaching and fixing the printing plate film made of a resin on to the printing base of the printing machine.
