摘要： Photopolymerizable elements are described comprising a sheet support, a photopolymerizable layer having a thickness of, at most, 0.0006 inch (0.015 mm.) and an optical density of at least 3.0 in the actinic region. Resist images made from these elements may be etched by a process of chemically undercutting the image areas and then spraying or rubbing them. At least two dot-etched photopolymerizable elements, each exposed through a different color separation negative and colored accordingly, are placed in registration to form a color proofing system.

摘要： In a process for laminating a photosensitive layer to a aluminum or copper substrate surface by means of nip rolls, the improvement comprising the sequential steps of:(a) rendering the substrate surface clean, as defined by the uniform water film test;(b) within about 1 minute after rendering the substrate clean and immediately prior to lamination, applying a thin layer of liquid to form an interface between the substrate surface and the photosensitive layer;(c) displacing the thin layer of liquid from the interface by absorption into the photosensitive layer during lamination, and(d) within 30 seconds after lamination, removing the support for the photosensitive layer without delamination of the photosensitive layer from the substrate by bending the support back along a longitudinal axis of the photosensitive layer.

摘要： A dry-developing dry film resist is provided comprising a photopolymerizable layer preferably sandwiched between a support sheet and a cover sheet, the layer comprising polymerizable monomer in excess of the absorptive capacity of the layer, photopolymerization initiator, and binder component of a plurality of polymers, at least one of these polymers being incompatible so as to be present as a dispersion in the layer to reduce the cohesive strength of the layer. The layer is developed by peeling away the support sheet, the unexposed area of the layer adhering to the support sheet and the exposed area adhering to the substrate to which it was laminated to form a resist image against such treatments as etching, plating and soldering, especially to make a printed circuit.
