<p>1. A process for the production of relief copies, in which the photopolymerizable layer of a copying material, which layer contains a polymerizable compound with at least two terminal ethylenically unsaturated double bonds, a polymeric binder and a photoinitiator which on exposure can generate free radicals, is exposed imagewise and thereafter the unexposed areas of the layer are washed out be means of a developer, characterized in that the layer is warmed for a period of 5 seconds to 10 minutes to temperature within the range from 50 to 180 degrees C after exposure, and is then developed.</p> |
