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.

The method involves the image-wise heat transfer of a reducing agent from a donor element to a receiving layer of a receiving element. The receiving element contains a thermoreducible silver source such as e.g. silver behenate. The process of the present invention provides high density images with multiple intermediate density levels.
