ABSTRACT:
The present invention is directed to lithographic printing plates that are suitable for imaging by laser discharge using laser ablation. The lithographic printing plates according to the present invention comprise a vacuum deposited polymeric layer comprising polyvinylpyrrolidone having a thickness of up to about 6000 Angstroms, an absorbing layer underlying the first layer that absorbs infrared radiation and has a thickness in a range between about 100 and about 500 Angstroms, and a substrate underlying the absorbing layer. The polymeric layer and the substrate exhibit different affinities for at least one printing liquid selected from the group consisting of ink and an adhesive fluid for ink.
