ABSTRACT:
A durable planographic driographic printing plate comprising a substrate having a highly abhesive layer thereon which is capable of repelling oleo ink when dry, and photobonded to the abhesive layer in image areas an oleo-ink receptive polymer layer. The photobonding occurs during imaging of the plate by including within the abhesive layer ethylenically unsaturated groups which are copolymerizable with a light-sensitive ethylenically unsaturated free radical initiated photopolymerizable material which provides the ink receptive image areas upon exposure.
