Abstract
The present invention refers to a light-sensitive silver halide multilayer color photographic element having a support base and coated thereon blue-, green- and red-sensitive silver halide emulsion layers respectively associated with non-diffusing yellow, magenta and cyan dye-forming couplers, wherein at least one green-sensitive layer contains a 2-equivalent 3-anilino-4-phenylthio-5-pyrazolone magenta coupler and a 4-(4-hydroxy-phenylazo)-5-pyrazolone colored magenta coupler. The multilayer color photographic element of the present invention presents an improved speed and contrast, without a detrimental effect on the other sensitometric properties, such as Dmin and Dmax.
