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 solution of a binder material is applied in a controlled manner to enable the mixed powder particles to stick together but without leaving much residue in the final composition. With this process, the mixed powder and agglomerates each have desired uniformity in size and chemical composition. The resulting dry uniformly mixed composition is highly stable, dissolvable and substantially free of dust.
