ABSTRACT:
Stabilizer precursors which comprise triarylphosphines and triarylphosphoranes and which, upon being heated to a temperature above about 100.degree. C., release a phosphorous compound silver halide stabilizer that is useful in a heat stabilizable photographic silver halide material comprising photographic silver halide. A stabilized image is produced in the photographic material following exposure and development by heating the material to processing temperature. The triarylphosphines and triarylphosphoranes are useful in a dry physical development photographic material and process. Alternatively, the triarylphosphines and triarylphosphoranes are useful in a dry chemical photographic material and process.
