Abstract (en)
A method of preparing a silver halide light-sensitive photographic material incorporating layers of emulsions precipitated in colloidal silica serving as a protective colloid. The silver halide emulsion either or not being chemically sensitized in the presence of a spectral sensitizer is less subjected to pressure phenomena, even for thin coated layers, highly sensitive and rapidly processable. Its higher coverage power after development permits the coating of less silver, resulting in a customer-friendly consumption of less chemicals.
