Abstract: Provided is a multilayer, multicolor overlay proof comprising at least one precolored overlay image and at least one toned overlay image, as well as a process for preparing such an overlay proof.

Abstract: Method of providing an image-bearing surface, e.g., a pre-press proof, with a protective covering, comprising laminating to said surface a thin, substantially transparent integral polymeric film, the improvement wherein the polymeric film consists essentially of a mixture of at least two slightly incompatible polymers, whereby the film exhibits a 20.degree. specular gloss that is at least 5% lower than the gloss of a film prepared from any one of said polymer constituents.

Abstract: This invention relates to an image reproduction process, more particularly a color proofing process, which utilizes a peel-apart photosensitive element comprising a strippable coversheet, a photohardenable layer, an elastomeric layer, and a support, to produce a positive image of the transparency on the coversheet and a negative image of the transparency on the elastomeric layer.

Abstract: This invention relates to a process for preparing a reverse image using a pigmented peel-apart element containing a photoinhibitor. More particularly this invention relates to a process for preparing a negative or reverse surprint proof using peel-apart photosensitive elements comprising a strippable cover sheet; a photoadherent layer containing a colorant and a photoinhibitor compound; a tacky, essentially nonphotosensitive contiguous layer; and a support.

Abstract: Nomenclature is applied to a soldermask surface employing a peel apart film prior to application of molten solder.

Abstract: Process for preparing a surprint proof using an imagewise exposed peel apart photosensitive element comprising a strippable cover sheet, a photoadherent layer containing a colorant, a tacky nonphotosensitive contiguous layer, and a support wherein after peeling apart, if exposed through a separation negative, a positive colored photoadherent image on the cover sheet is adhered to a substrate, or, if exposed through a separation positive, a positive colored photoadherent image on the supported contiguous layer is adhered to a substrate. By repeating the process different colored layers can be built upon the substrate to form the surprint proof.

Abstract: A negative-working dry peel apart photopolymerizable element consisting essentially of a photopolymerizable layer between a support and cover sheet, the photopolymerizable layer containing (1) at least two halogen-free polymeric organic binders, (2) a photoinitiator system and (3) at least one monomer present in an amount in excess of the absorptive capacity of the binders for the monomer, at least one polymeric binder which is incompatible in the layer contains 0.5 to 40.0% by weight of polyvinylformal based on the total weight of polymeric binder and is present as a dispersed phase in the layer. The element is useful in color projection transparencies, seismic readout and as photoresists.
