ABSTRACT:
The present invention relates to a process for preparing a multicolored proof, using a radiation-sensitive recording material which comprises a temporary, sheet-shaped layer support, a thermally transferable layer containing a colorant in one primary color and a radiation-sensitive layer. The process comprises the steps of: a) exposing the recording material imagewise b)developing the exposed layer with an aqueous-alkaline solution to uncover the thermally transferable image areas, and c) contacting the coated side of the recording material with an image receptor and transferring the transferable image areas to the image receptor, with the application of heat and pressure, to produce a partial image in the first primary color. The above-described process steps are repeated at least once, using a radiation-sensitive recording material which contains a colorant in another primary color in its thermally transferable layer. Depending upon the respective embodiment, the process of the invention yields a proof which can be produced by a positive, a negative or a digital method, without distorting the image thus generated by interjacent layers.
