Abstract
A magenta dye-forming pyrazolotriazole coupler solubilized by one or two sulfonamido groups results in a coupler having increased coupling activity, low fog and good dispersability. The couplers are useful in photographic elements and react with oxidized silver halide to form dyes, and/or to release photographically useful groups.
