Photographic element containing an improved pyrazolotriazole coupler |
| abstract |
The invention provides a photographic element comprising a light sensitive silver halide emulsion layer having associated therewith a dye-forming coupler having formula I:n whereinn R 1 is selected from the group consisting of alkyl, aryl, and heterocyclic groups; R 2 is selected from the group consisting of hydrogen, alkyl, aryl, and heterocyclic groups; W is C(O) or S(O) 2 ; R 3 is selected from the group consisting of alkyl and aryl groups having a calculated logP of at least 9; Y is a substituent; and X is H or a coupling-off group. |
