    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 for use in thermal transfer printing. The donor element comprises on a support a donor layer comprising a binder and a mixture of at least two thermotransferable reducing agents 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. By using a mixture of reducing agents crystallization is reduced and the obtained images exhibit an increased density and a more neutral grey hue.

    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.
