ABSTRACT:
Transfer sheets are provided which include a polyethylene imine as a blocking agent and which are useful in the heat transfer dye printing of various materials such as textiles. The polyethylene imine is capable of completely or partially blocking the transfer of sublimable dyes which have been imprinted on the transfer sheet while having no effect on other dyes which also have been imprinted on the transfer sheet. By using such transfer sheets, designs can be printed which are not otherwise obtainable by conventional techniques. The invention further concerns the method of making such sheets, their use in the printing of various materials, and the materials which have been so printed.
