ABSTRACT:
This invention comprises a process for generating particles of MAg.sub.4 I.sub.5, wherein M is a monovalent cation, which comprises dissolving AgI and MI in a polar solvent followed by precipitating particles of MAg.sub.4 I.sub.5 by adding the solution to a nonpolar solvent. The resulting MAg.sub.4 I.sub.5 is in the form of anisotropic crystalline particles. The MAg.sub.4 I.sub.5 particles can be used in the preparation of a photothermographic element. The invention also comprises method of preparing a stable aqueous emulsion of MAg.sub.4 I.sub.5 particles.
