| Title of Invention | THERMAL MASS TRANSFER IMAGING METHOD AND DONOR ELEMENT FOR USE THEREIN |
|---|---|
| Abstract | There is described a thermal recording system which utilizes a donor element comprising a substrate and a thermal transfer material layer having a dye-containing phase which is amorphous and wherein the dye or dyes present in the amorphous phase form a continuous film. Imagewise heating of the medium transfers portions of the transfer layer to a receiver sheet, thus forming an image. The transfer layer may also include a non-dye phase comprising a thermal solvent. During the heating of the donor element, the crystalline thermal solvent melts and dissolves or liquefies at least a portion of the dye-containing phase, thereby lowering the temperature at which transfer of the transfer layer occurs. |
