ABSTRACT OF THE DISCLOSURE A process for preparing a color proofing sheet is disclosed. The process comprises imagewise exposing a light-sensitive image-forming material comprising a transparent support having provided thereon a dye- or pigment-containing light-sensitive photoresist composition layer or both a dye or pigment-containing colorant layer and a light-sensitive photoresist composi- tion layer through a color separation mask, developing the material to form a color separation image, transfer- ring the color separation image onto a photopolymerizable image-receiving layer, transferring in registration at least one more color separation image onto the same image- receiving layer to obtain a multicolored color proofing sheet on a single support, and totally exposing the image-receiving layer after the image transfer in an amount sufficient to induce photopolymerization thereof. A color proofing sheet realizing color reproduction essentially the same as actual print copies and has a good image strength and non-tackiness can be obtained by the process.
