ABSTRACT:
A dye-receiving element for thermal dye transfer suitable for forming a focussing tool comprising a polymeric central dye image-receiving section having a substantially planar image receiving surface and a relatively thicker integral polymeric frame section extending around the periphery of said central section, said image receiving surface being formed at an inclined angle relative to the frame section. The invention further includes a process of forming an imaged focussing tool by the steps of a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer, and b) transferring portions of the dye layer in a pattern corresponding to a desired focussing image to a dye-receiving element as described above, and imaged focussing tools obtained by such a process.
