ABSTRACT:
A process for forming a line art of halftone multicolor colloid pattern involves the contact exposure in registration of different colored silver halide emulsion hydrophilic colloid layers each on a temporary support and the hardening development of the individual exposed silver halide emulsion layers in turn after each is transferred to a common intermediate support to form thereon a multi-layer assembly of reverse reading color relief images on top of each other. This assembly together with an underlying stripping layer from the intermediate support is transferred bodily onto a permanent support by adherence to an adhesive layer carried on the latter support to form thereon a right-reading multicolor image that may serve as a color proof.
