| titleOfInvention | Photographic element |
| abstract | Photographic elements are described havingn a silver halide emulsion layer, a 2-equivalent 5-pyrazolone coupler in reactive association with said silver halide emulsion, and a competitor for oxidized developer in reactive association with said coupler having the formula:n nwherein R 1 represents an electron donating group, R 2 represents hydrogen, alkyl, alkoxy, aryl, aryloxy, aralkyl or amino of the formula -NHR 3 , where R 3 is phenyl or benzyl, with the proviso that at least one of the substituents R 1 and R 2 (a) represents (1) a ballast group of sufficient size as to render the hydrazide compound non-diffusible in the photographic element prior to development in alkaline processing solution and (b) comprises a polar group, and n is 0, 1 or 2. |
