Abstract

Photopolymerizable laminates suitable for producing flexible and resilient printing plates carry on a dimensionally stable base at least one intermediate layer and on top thereof a photopolymerizable layer which consists essentially of a mixture of a water-soluble copolymer or derivative of polyvinyl alcohol, a specific copolymerizable mono-functional (meth)acrylate, a photoinitiator and a thermal polymerization inhibitor.
