ABSTRACT:
A dyesheet for thermal transfer printing comprises a substrate supporting a transfer coat comprising a plurality of uniform panels containing different colored thermally transferable dyes, and a further panel in which instead of a colored dye there is a thermally transferable colorless absorber of ultraviolet radiation. Using such a dyesheet, a layer of UV absorber can be applied very simply as an extension of the printing process, by causing the receiver to pass through the printer once more, in contact with the further panel, essentially as though the UV absorber were merely a further color to be added to the print.
