ABSTRACT:
The present invention provides a method for reproducing continuous tone images by means of a thermal head. 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.
