Abstract: The present invention relates to a processing solution supply cartridge which utilizes a single container for a single-part developer concentrate. The single container has at least two valves or necks and is adapted to be utilized on a existing processor or processing machine. The single developer container design of the present invention assures a complete emptying of the container by permitting the simultaneous replenishment of single-part developer through each of the valves into the processing machine. With the combination of the single developer container and the single-part developer the process of metering distinct developers through distinct containers is not required. By facilitating the complete emptying of the developer container, the likelihood of developer solution remaining in the container is minimized.

Abstract: Photographic bleach-fixing solutions in a processing chamber can be directly replenished using a single-part photographic bleach-fixing “precursor” composition that comprises one or more iron-ligand complexes, one or more thiosulfates as the sole fixing agents, and optionally, a sulfite preservative. At least 50 mol % of the iron in the composition is in the form of Fe(II). Immediately prior to or during directly supplying the precursor composition to the processing chamber from an enclosed container, sufficient ferrous ions are converted to ferric ions to provide desired bleaching in the processing chamber.

Abstract: The invention provides a color negative photographic element comprising a transparent support bearing at least two light sensitive silver halide emulsion layers sensitive to blue light, at least two such layers sensitive to green light, and at least two such layers sensitive to red light, wherein at least one of the red sensitive emulsion layers is spectrally sensitized with both a particular first carbocyanine dye (I) which contains both a thiazole and an oxazole ring and a particular second carbocyanine dye (II) which contains two thiazole rings.The element of the invention is advantageous in allowing an increased efficiency of silver removal during the bleaching step of the development process.

Abstract: This invention provides a method of processing a negative color silver halide photographic element comprising taking an exposed color silver halide photographic element with a speed greater than ISO 180 or containing at least one spectrally sensitized silver halide emulsion with a tabularity greater than 100, wherein the photographic element comprises a total amount of incorporated silver and incorporated vehicle of 20 g/m.sup.2 film or less; developing the exposed photographic material; and bleaching the exposed, developed photographic element with a peracid bleach in the presence of a bleach accelerator.

Abstract: A process for rapidly forming a laminar ceramic shell mold on a supporting structure comprising alternately, in either order, the steps of: (1) dipping the support structure into a bath comprising either an alkali stabilized solution of ionic silicate or an alkali stabilized solution of colloidal silica to define a first coating on the support structure; and (2) dipping the support structure into a bath comprising an acid stabilized solution of phosphate modified aluminum salt to define a second coating on the support structure. The coatings on the support structure react to form a gel set shell which can be fired to create a ceramic material. The dipping step sequence is repeated to provide additional coatings which react to define additional layers of gel set shell. The rate of laminate thickness buildup can be increased by including fine particulate refractory in the coating baths and the coated surface can be contacted by dry, relatively coarse refractory to define a stucco layer between the dip coatings.
