[PROBLEMS] To optimize adhesion to a photosensitive resin layer, infrared ablation efficiency, removal efficiency of an infrared sensitive layer during plate making development, etc. in a digital version of a water-based development photosensitive resin printing plate. . An aqueous development photosensitive resin printing original plate in which at least a support (A), a photosensitive resin layer (B), and an infrared sensitive layer (C) that can be processed by infrared rays are laminated in this order, is infrared sensitive. By using two or more binder components in the layer, it is possible to optimize the adhesion to the photosensitive resin layer, the ablation efficiency with infrared rays, the removal efficiency of the infrared sensitive layer during plate making development, and the like.
