ABSTRACT:
A photographic element containing a silver halide emulsion layer having associated therewith, a dye-forming coupler and a dye stabilizer which has a melting point of less than 150.degree. C. (and preferably less than 100.degree. C.) and is of the formula: ##STR1## wherein R, m, q, X, Y, r, and (R.sup.7).sub.n are defined in the specification.
The element particularly contains a coupler which forms a yellow dye upon reaction with oxidized developer. A method of making stabilizers of the above type using particular solvents and a non-aqueous workup, is also provided.
