Abstract

A process for producing a colored image by laminating a light-sensitive material comprising a temporary support film (i), a colored light-sensitive layer and a heat-activable adhesive layer onto an image-receiving material at elevated temperature and under pressure, subjecting the light-sensitive layer to imagewise exposure and developing by peeling off the support film, characterized in that the image-receiving material comprises a light-sensitive compound which, on irradiation, releases a gas which remains trapped in the image-receiving material in the form of gas bubbles. The advantage of the process is that, on irradiation under a halftone original, the size of the halftone dots in the coloured image produced on such an image-receiving material is optically reduced.
