(57) [Summary] (Modified) [Structure] Substrate, diazonium salt polycondensation product, compound capable of polymerizing by free radical, photosensitive layer comprising photoinitiator and polymer binder, and oxygen in atmosphere A light-sensitive recording material comprising a top coat containing a water-soluble polymer having low permeability to water and a water-soluble phosphate compound, particularly ammonium monophosphate, sodium phosphate or potassium phosphate. [Effect] It is possible to provide a photosensitive recording material, which is characterized by high photosensitivity, long shelf life, and low adhesive tendency, and which is particularly suitable for producing a lithographic printing plate for printing a large amount. |
