A photopolymeriziable composition which comprises poly butane diol diacrylate, a photoinitiator and a binding resin. Upon coating the composition onto a substrate a photographic element is formed which does not require the presence of an oxygen barrier layer.

This invention relates to photosensitized sheet constructions which, upon exposure to an actinic radiation source through a screened image, can accurately reproduce said image. The construction is useful as a color proofing film which can be employed to accurately predict the image quality from a lithographic printing process. This system allows the operator to use either a full layer transfer or an image transfer method of color proofing.

Light sensitive coating compositions containing a dyestuff, which compositions exhibit improved adhesion to transparent film substrates, are disclosed. For example, the adhesion between a polyester base film and a light sensitive coating composition containing a light sensitive diazo material, a resinous binder and a dyestuff is improved by additionally incorporating into the composition an effective amount of an adhesion promoter based on a copolyester obtained by the esterification and subsequent polymerization of a lower alkylene glycol with a mixture of terephthalic acid, isophthalic acid, and at least one acyclic dicarboxylic acid. These coating compositions may be readily removed from the base film by appropriate lithographic developer solutions without substantial residual staining of the film by the dyestuff present in the coating composition.

The invention provides a photographic element having a substrate and a photosensitive coating on the substrate, said coating containing (A) the polycondensation product of 3-methoxy-4-diazodiphenyl amine sulfate and 4,4'-bis-methoxy methyldiphenyl ether, precipitated as methane sulfonate; and, (B) the polycondensation product of 3-methoxy-4-diazodiphenyl amine sulfate and 4,4'-bis-methoxy methyldiphenyl ether, precipitated as mesitylene sulfonate, and (C) at least one colorant: and (D) at least one water soluble polymeric binding resin which is preferably polyvinyl pyrrolidone. The element is developable using water alone as a solvent.

A process for making a multicolored reproduction combining overlay and surprint characteristics in which a photohardenable layer, such as a photopolymerizable layer, is cast on a semi-rigid, transparent, support film, the photohardenable layer is exposed in an appropriate exposure unit through a color negative representing one color, the exposed layer is developed to remove the unexposed areas and leave the exposed image areas, an adhesive layer, such as an acrylic adhesive, is coated on a release sheet, the coated release sheet is contacted with a receptor sheet at a temperature and pressure sufficient to transfer the adhesive to the sheet, the developed layer is contacted with the adhesive coated sheet at a temperature and pressure sufficient to transfer the image areas to the sheet and the steps of casting a photohardenable layer, exposing the layer, developing the layer and contacting the image areas with the sheet is repeated for each additional color desired.
