A heat transfer printing sheet wherein a pattern comprising a basic dye having a poor heat transferable property, an oxidizing agent having the property of increasing the heat transferable property of the basic dye and a binder is formed on a base support sheet and a process for heat transfer printing wherein the above heat transfer printing sheet is brought into contact with a material to be transfer printed with the surface of the heat transfer printing sheet which contains said pattern, and the whole is heated under a pressure to effect the transfer of the basic dye but not of the oxidizing agent and the binder and then the heat transfer printing sheet is peeled off from the latter to transfer print the optional pattern onto said material. The pattern can comprise two layers in which one comprises the basic dye and the binder and other comprises the oxidizing agent and the binder. The base support sheet can be formed of a resin film through which the basic dye cannot be passed when the heat transfer printing is not carried out. The pattern can be coated with a resin film through which the basic dye cannot be passed when the heat transfer printing is not carried out, but can be passed when the heat transfer printing is carried out.
