    摘要: The present invention provides a method of hardening a proteinaceous layer of a photographic silver halide element by incorporating a modified dextran in said proteinaceous layer, said modified dextran being the reaction product of dextran and an alkyl haloformate, a substituted alkyl haloformate, an aryl haloformate, or a substituted aryl haloformate. The invention also provides a photographic element comprising a said reaction product in at least one proteinaceous silver halide emulsion layer and/or in another proteinaceous layer coated thereon.
