ABSTRACT:
Water-developable positive acting lithographic printing plate. The plate is prepared by first coating a substrate with an oleophilic composition, drying and curing the composition to form an insoluble adhering oleophilic layer and then overcoating said oleophilic layer with a water soluble photopolymerizable composition. Upon imagewise exposure of the plate, the photopolymerizable composition polymerizes in the non-image areas. Upon development with ordinary tap water, the unpolymerized image areas of the photopolymerizable composition are washed away, leaving an oleophilic surface in the image areas and a hydrophilic surface in the background.
