Abstract
Disclosed is color silver halide photographic element comprising a light-sensitive silver halide emulsion layer or a non-silver containing light-insensitive layer, said light-sensitive or light-insensitive layer containing a polymer compound comprising a repeating benzotriazole subunit wherein a) the benzotriazole monomer corresponding to the benzotriazole subunit has a Calculated logP of at least 3.1 and less than 6.2; or b) the benzotriazole monomer corresponding to the benzotriazole subunit has a Calculated logP of less than 3.1 and the polymer additionally comprises a co-monomer with Calculated logP of 0.5 or greater, and the amount of the polymer compound in the element is sufficient to increase the photographic speed of the element compared to the same element without the polymer compound.
