A tabular silica dispersion is disclosed, which is obtained by mixing a tabular silica, gelatin, a cyclodextrin and a compound capable of crosslinking gelatin. Silver halide photographic materials are also disclosed, in which the tabular silica dispersion is incorporated into a silver halide emulsion layer or a light-insensitive hydrophilic colloidal layer.

Tabular silica dispersion and silver halide photographic light sensitive

Disclosed is a silver halide photographic light sensitive material comprising a support and provided thereon, a light sensitive silver halide emulsion layer and a non-light sensitive hydrophilic binder layer, wherein at least one of the light sensitive silver halide emulsion layer and the non-light sensitive hydrophilic binder layer contains tabular silica particles covered with a hardened gelatin layer.

Silver halide photographic light sensitive material

A silver halide photographic element with enhanced sensitivity and improved pressure resistance is disclosed, comprising a support having, on at least one side thereof, hydrophilic colloidal layers including a light-sensitive silver halide emulsion layer and a nonlight-sensitive hydrophilic colloidal layer, wherein the nonlight-sensitive layer contains organic material-aggregation particles; and gelatin contained in the total hydrophilic colloidal layers provided on one side of the support amounts to a range of 1.3 to 2.5 g per m.sup.2.
