    摘要： The present invention provides a method for making an image comprising the steps of:bringing a dye-layer comprised on the support of a dye donor element in face-to-face relationship with an image receiving layer comprised on a support of an image receiving element, said dye layer consisting of a repeating sequence of at least two dye frames each containing a dye dispersed or dissolved in a binder and,image-wise heating by means of thermal head each of said dye frames of said repeating sequence so as to cause image-wise transfer of dye from said dye layer to said image receiving layer characterised in that: said dye frames contain (a) particle(s) protruding from said dye layer, the last dye frame to be image-wise heated from said repeating sequence, containing said particle(s) in a reduced amount relative to the amount of said particle(s) in any of the other dye frames of said repeating sequence or alternatively said last dye frame being substantially free of said particle(s).

    摘要翻译： 本发明提供了一种制作图像的方法，包括以下步骤：将包含在染料供体元件的载体上的染料层与包含在图像接收元件的载体上的图像接收层面对面地进行关系 所述染料层由至少两个染料框架的重复序列组成，每个染料框架各自含有分散或溶解在粘合剂中的染料，并且通过所述重复序列的所述染料框架中的每个所述染色框架的热敏头进行成像加热，以产生图像 染料从所述染料层向所述图像接收层的转移方向为：所述染料框架包含（a）从所述染料层突出的颗粒，从所述重复序列加成图像的最后染料框架， 相对于所述重复序列的任何其它染料框架中的所述颗粒的量减少的量含有所述颗粒，或者所述最后一个染料框架基本上不含所述颗粒。

    摘要： The present invention provides a printing process using a donor element and a receiving element. The donor element comprises on a support a donor layer comprising a binder and a thermotransferable strong reducing agent capable of reducing a silver source to metallic silver upon heating.The donor element is image-wise heated while being in contact with an image receiving material comprising a thermoreducible silver source and a weak reducing agent, only being capable of reducing a silver source to metallic silver in the presence of metallic silver formed by said strong reducing agent. Image density is increased and stability of the reductor donor element can be improved.

    摘要： The present invention provides a donor element comprising on a support a donor layer comprising a binder, a thermotransferable reducing agent capable of reducing a silver source to metallic silver upon heating and a thermotransferable dye. When such a donor element is used in a thermal transfer printing process in conjunction with a receiving element having a receiving layer that contains a thermoreducible silver source, an image of a neutral black tone and having a high optical density is obtained.
