Abstract:
1. A photosensitive resin printing plate precursor for letterpress printing comprising, on a support in this order: a photosensitive resin layer (A) containing a water-soluble or water-dispersible resin and an ultraviolet-curable monomer; optionally, an adhesion-adjusting layer (B) containing a water-soluble or water-dispersible resin; a water-insoluble heat-sensitive mask layer (C) containing an infrared-absorbing material, a peel assist layer (D) having a thickness of 0.1 to 6 μm, and a protective layer (E), wherein the absence of the adhesion-adjusting layer (B), the water insoluble heat-sensitive mask layer (C) is formed in contact with the photosensitive resin layer (A), and in the presence of the adhesion-adjusting layer (B), the water-insoluble heat-sensitive mask layer (C) is formed in contact with the adhesion adjusting layer (B).
