ABSTRACT:
The invention provides a color negative photographic element comprising a transparent support bearing at least two light sensitive silver halide emulsion layers sensitive to blue light, at least two such layers sensitive to green light, and at least two such layers sensitive to red light, wherein at least one of the red sensitive emulsion layers is spectrally sensitized with both a particular first carbocyanine dye (I) which contains both a thiazole and an oxazole ring and a particular second carbocyanine dye (II) which contains two thiazole rings.
The element of the invention is advantageous in allowing an increased efficiency of silver removal during the bleaching step of the development process.
