Abstract
A process for the production of a photopolymerizable recording material comprised of a layer support and a solid, dry photopolymerizable layer which contains, as the essential constituents: (a) a polymeric binder which is insoluble in water and soluble in aqueous-alkaline solutions, (b) an acrylic or methacrylic acid ester of a polyhydric alcohol, which is polymerizable by a free-radical process, and (c) an initiator capable of photo-inducing the free-radical polymerization, in which process the photopolymerizable layer is treated with ammonia or an oxidizing agent. This treatment substantially reduces the cold flow of the layer.
