A thermal stencil master sheet for stencil printing has a thermoplastic synthetic resin film which is perforatable with heat and a porous substrate, which is substantially unchanged by the heat. The film is bonded to the substrate with a urethane adhesive, preferably composed mainly of a specific urethane prepolymer obtained by reacting a polyether diol with a diisocyanate so as to give an equivalent ratio of NCO/OH of at least 1.1. |
