ABSTRACT:
A powdered, uniformly-mixed photographic processing composition is prepared with intense mixing of dry photoprocessing chemical components, and by forming uniformly sized agglomerates of the mixed powder. During agglomeration, a hot melt binder polymer is applied in a controlled manner to enable the uniformly-mixed powder particles to stick together with little residue in the final composition. With this process, the mixed powder and agglomerates each have the desired uniformity in size and chemical composition. The resulting dry composition is highly stable, dissolvable and substantially free of dust.
