摘要:
A lithographic process comprises the steps of imagewise heating a presensitized lithographic printing plate and removing an unheated area of an image-forming layer to form a lithographic printing plate. The presensitized lithographic printing plate comprises a hydrophilic support and the image-forming layer. The image-forming layer contains a compound or a polymer having o-quinodimethane structures or precursor structures thereof. The lithographic printing plate is prepared by a reaction of the o-quinodimethane structures.
