ABSTRACT:
Water coatable and water developable negative-acting color proofing single sheet and overlay systems are described. The water-soluble photosensitive color layer employed in each type of proofing construction includes a photopolymerizable polymer having a weight-average molecular weight between 5,000 and 100,000; an alkaline soluble resin having a weight-average molecular weight between 1,000 and 200,000 and an acid number between 50 and 300; and a water-soluble photoinitiator.
