THERMAL TRANSFER RECORDING SYSTEM HAVING AMORPHOUS DYE PHASE

摘要

PROBLEM TO BE SOLVED: To provide a novel thermal transfer recording system capable of utilizing a relatively thin donor layer and a receiver sheet having a relatively smooth and glossy surface.

SOLUTION: 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 a portion 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.
