Color photographic element containing speed improving compound in combination with reflecting material

Abstract

Disclosed is a color silver halide photographic element comprising a support bearing: (1) a light sensitive silver halide emulsion layer; (2) a nitrogen heterocycle with a minimum of three heteroatoms that does not react with oxidized developer, does not contain free thiol substituents, and has a ClogP sufficient to increase the photographic speed of said element compared to the same element without the compound, said heterocycle compound located either in said light sensitive layer or in a layer adjacent to it; and (3) a light reflecting silver halide material; provided that the heterocycle compound and the light reflecting material are located either (a) in different layers of the element located close enough to each other so that a super-additive speed increase is realized or (b) in the same light sensitive layer. The invention provides improved light sensitivity.
