    • A process of controlling the gloss of a thermal dye transfer image comprising: (a) imagewise-heating a dye-donor element comprising a support having thereon a dye layer comprising an image dye in a binder, the dye-donor being in contact with a dye-receiving element, thereby transferring a dye image to an image-receiving layer of the dye-receiving element to form the dye transfer image; and (b) thermally transferring a protection layer on top of the transferred dye image, the protection layer being applied from an element which contains unexpanded synthetic thermoplastic polymeric microspheres, the microspheres having a particle size in the unexpanded condition of from about 5 to about 20 &mgr;m, the protection layer being transferred using a given energy level in order to expand the microspheres until a desired gloss level is obtained.
    • 一种控制热染料转移图像的光泽度的方法,包括:(a)对染料供体元件进行成像加热,所述染料供体元件包括其上具有染料层的载体,所述染料层包含粘合剂中的图像染料,所述染料供体与 染料接收元件,从而将染料图像转印到染料接收元件的图像接收层以形成染料转移图像; 和(b)在转印的染料图像的顶部上热转印保护层,保护层由含有未发泡的合成热塑性聚合物微球的元素施加,所述微球的未膨胀条件下的粒径为约5至约20 妈妈,使用给定能量水平转移保护层,以便扩大微球直至获得所需的光泽度。
