ABSTRACT:
A color photographic silver halide negative working duplicating element and process comprising (A) a magenta colored masking coupler in at least one blue-sensitive photographic silver halide emulsion layer; and (B) a combination of (i) masking couplers and (ii) color contamination of at least one photographic silver halide emulsion layer enables upon exposure and processing of the element formation of a duplicate image that enables formation of a print image that is visually indistinguishable from the original image. The color photographic silver halide duplicating element is useful in forming duplicate images, especially for color motion picture films.
