A process for the production of a color image is described, in which a photosensitive material that has a temporary support film, a colored photosensitive layer and an adhesion-promoting layer that can be activated by heat is laminated at high temperature and under pressure with an image-receiving material which carries, on a support, a pigment layer containing a white pigment. The photosensitive layer is exposed imagewise and developed to produce an image, the temporary support film is peeled off from the image-receiving material before or after exposure to light and, if required, these steps are repeated with at least one further photosensitive material whose colored layer has another color to produce a multi-colored image. The process gives color images having a smaller dot enlargement compared with a halftone original and is particularly suitable for the color testing of copy for multicolor printing.
