<p>A thermal stencil paper for mimeograph comprising a porous support and a plastic film laminated on each other. The thermal stencil paper for mimeograph of this invention contains a novel release layer on the plastic film. The release layer is composed of a specific graft polymer whose branch polymer comprises a fluorocarbon or silicone resin. The graft polymer is prepared by copolymerizing a radically polymerizable monomer constituting a backbone polymer of said graft polymer and a radically polymerizable fluorocarbon or silicone prepolymer which has a polymerizable double bond at one terminal end of its polymer chain.</p>
