PURPOSE:To obtain a silver halide photosensitive material having substantial performance to prevent electrostatic charge, good tape adhesiveness and type printability and excellent film strength by forming a specific back coat layer on the surface of a hydrophobic substrate on the side opposite from the surface on which a silver halide photographic constituting layer is provided. CONSTITUTION:The back coat layer of the AgX photographic material having at least one layer of silver halide (AgX) photosensitive layer on one surface of the hydrophobic substrate and provided with the back coat layer on the surface on the side oppositve therefrom is formed by incorporating a) a synthetic binder, b) inorg. antistatic agent, c) compd. having >=2 epoxy groups or ethyleneimino groups in a molecule, d) polyvalent metal, for example, the salt or complex of Cr or Zr and adjusting the pH of a coating liquid for back coating to >=6.0, more preferably >=7.0. Such back coat layer is provided on the AgX photosensitive material, by which the generation of static marks is obviated and the difficultly in handling as a result of sticking to each other in a processing stage or the staining of an installation, etc. are obviated. The disappearance of the type print formed on the rear surface during processing is obviated as well. |
