Abstract: A planographic printing plate precursor comprises: a support; and a recording layer disposed on the support, the recording layer comprising a lower layer and an upper layer disposed on the lower layer, wherein the lower layer contains a resin having in a main chain structure a phenol skeleton and a urea bond, the upper layer contains a water-insoluble alkali-soluble resin and an infrared absorber, and the solubility of the upper layer in an aqueous alkali solution is increased by exposure. The planographic printing plate precursor can be produced directly through scanning exposure based on digital signals. It is superior in reproducibility of highly fine images and also superior in printing durability and chemical resistance of small-area image areas such as halftone dots and thin lines.

Abstract: The present invention relates to a positiive-working presensitized plate useful for preparing a lithographic printing plate comprising a positive-working photosensitive composition comprising at least one ester of 1,2-naphthoquinone-2-diazide-5-sulfonic acid, at least one ester of 1,2-naphthoquinone-2-diazide-4-sulfonic acid, and at least one polymer which is insoluble in water and soluble in an aqueous alkaline solution and which comprises at least one group or bond selected from sulfonamide group, urea bond or urethane bond. A lithographic printing plate prepared from the presensitized plate of the present invention shows improvement of chemical-resistance and printing durability, and good sensitivity, coupling property, adaptability to ball-point pen, shelf stability, and stability of sensitivity with time after exposure.
