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.
