Abstract
Abstract A vacuum package of a photographic processing composition consisting of a plurality of components is obtained by placing the components in a bag as separate solid state layers in a vacuum sealed manner. A normally liquid component is converted into a solid adduct in order to form a layer. A substantially water insoluble component or trace component is coated on the surface of particles of a water soluble inorganic compound, from which another layer is formed. The packaged composition is taken out of the bag and diluted with water to prepare a processing solution.
