    摘要: In a silver halide photographic material for tanning development, comprising a support base coated with a substantially unhardened hydrophilic binder layer including a light-sensitive silver halide emulsion reactively associated with a tanning developer and a dispersion of colloidal silver, the tendency of the hydrophilic binder to become water-insoluble during storage can be prevented by adjusting the pAg of the colloidal silver dispersion to values in the range from 6.5 to 9.5 with a 1-phenyl-5-mercaptotetrazole compound before coating.
