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 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.
本文描述了一种热记录系统,该系统利用一个由基片和热转印材料层组成的供体元件,热转印材料层具有无定形的含染料相,其中存在于无定形相中的染料形成连续的薄膜。介质的图像加热将转印层的部分转移到接收片上,从而形成图像。转移层还可包括由热溶剂组成的非染料相。在加热供体元件的过程中,结晶热溶剂会熔化并溶解或液化至少一部分含染料相,从而降低转移层发生转移的温度。
