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.

Abstract: Process for the production of a laminated article including a sheet support bearing a silver image produced by the silver complex diffusion transfer process in a layer containing developement nuclei, wherein such supported image is heat-laminated with a protective thermoplastic resin layer of sheet that covers it.

Abstract: An adhesive sealing strip for coiled or spooled recording materials, such as rolls of magnetic tape, in which the identification features, such as casting numbers, are clearly legible, is obtained by printing the features on an adhesive tape over the entire width of the web in lines one above the other and at the same time side by side in columns, each following column being offset vertically relative to the preceding column by a specific amount, whereupon the recording material is cut to the desired useful width. In this manner, a maximum height of printing of the identification features can be achieved in which the symbols are clearly legible (FIG. 3).
