摘要： The present invention relates to the use of fine metal particles for the recovery of silver from a silver-bearing photographic waste solution. In particular, the metal particles are encapsulated in a hydrophilic colloid that allows for the permeability of water and silver ions. When contacted with the silver-bearing photographic waste solution, the hydrophilic colloid will imbibe water and swell. At the same time, the silver ions can permeate the colloid matrix and come into contact with the metal particles, preferably iron particles, at which point a metal—metal exchange reaction takes place.

摘要： A method of providing photoprocessing services utilizes a packaging system in which photoprocessing solutions are distributed from a source of manufacture to a photofinishing site. The packaging system includes a rigid or semi-rigid outer container and at least one internal container. The internal container includes the processing solution, and can be made of a rigid or flexible material. The internal container may be separable from the outer container or may be in the form of an internal compartment that is integral with the outer container. As an option, the outer container can house a further container that is designed to collect waste or spent solution from the photoprocessing site. With the system of the present invention, a designated supplier entity can follow the packaging system through an entire usage cycle of the system.

摘要： A process for forming a silver halide photographic emulsion is disclosed comprising precipitating silver halide grains in an aqueous dispersing medium to which has been added silver and halide salt solutions while agitating the dispersing medium, wherein the precipitation is done in the presence of an antifoamant compound of the formula RO(CH2CH2O)nH wherein R represents an alkyl or alkenyl group containing 10 to 25 carbon atoms, or mixtures thereof, and n represents a mean value of from 2 to 4. The antifoamant material may be delivered to the aqueous dispersing medium as a small particle dispersion, made with the same peptizer used for manufacturing the emulsion or another stabilizer. A further embodiment of the invention is directed towards a silver halide photographic material comprising a support upon which is coated at least one light sensitive silver halide emulsion layer, comprising a silver halide emulsion precipitated in accordance with the described process.

摘要： The present invention is also directed to a method of photoprocessing a photographic imaging element having a processing-solution-permeable overcoat that comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble hydrophilic polymer. During photoprocessing, a surface-active water-soluble hydrophilic polymer is leached into a photoprocessing solution. However, foaming due to the hydrophilic polymer in the photoprocessing solution is prevented by the presence of a non-ionic surfactant having an HLB of less than 12.

摘要： A photographic element is disclosed comprising a film support, at least one light-sensitive layer, a highly loaded layer which contains more than 30 volume percent of non-film forming particulate material, and upper and lower aqueous coated adjacent layers which are next to the highly loaded layer, the upper adjacent layer being further from the support and the lower adjacent layer being closer to the support relative to the highly loaded layer, each adjacent layer having a film forming binder content of greater than 70 volume percent, and the lower adjacent layer being at least 1.0 micron thick. In accordance with a preferred embodiment of the invention, an imaging element having excellent adhesion characteristics is obtained in combination with excellent magnetic recording characteristics and photographic transparency where the non-film forming particulate material in the highly loaded layer comprises conductive particles, the layer adjacent to the highly loaded layer which is closer to the support comprises a hydrophilic curl control layer, and the layer adjacent to the highly loaded layer which is further from the support or a layer coated thereover comprises an aqueous coated transparent magnetic recording layer, by virtue of the physical flatness, low granularity, and optical density of the element. Also disclosed is a process for simultaneously applying a plurality of coating compositions comprising an aqueous magnetic recording layer coating composition, an antistatic layer aqueous coating composition, and a curl control layer aqueous coating composition, along with other optional conventional gelatin containing aqueous coated layers, onto a support. The placing of the highly filled antistatic layer between two aqueous coated adjacent layers, which in a preferred embodiment of the invention comprise a magnetic recording layer and a curl control layer or two curl control layers, results in excellent adhesion of the coated layers to the support compared to where the antistatic layer is closest to the support. The mechanical properties of a photographic element containing such a highly filled layer is substantially strengthened when the highly filled layer is sandwiched between the two other aqueous coated layers.

摘要： A process for making a direct dispersion of a photographically useful material is disclosed comprising subjecting a mixture of an aqueous gelatin solution, a liquid organic phase comprising a photographically useful material, and an ionic polymer to conditions of high shear or turbulence to form a fine dispersion of the organic phase having an average particle size of less than 0.5 micron dispersed in the aqueous solution; wherein the ratio of the organic phase viscosity to the aqueous gelatin solution viscosity in the absence of the ionic polymer, measured at the temperature of the dispersion forming step, is greater than a value of 2.0, and the ionic polymer is a water soluble or dispersible substantially non-surface active polyelectrolyte which has a molecular weight of at least 10,000 selected from: i) synthetic polymers derived from at least 5 mole % of monomers which contain --OSO.sub.3 M, --SO.sub.3 M, --COOM, or ---OPO(OM).sub.2 substituent groups where M represents a hydrogen atom or a cationic counterion, and ii) polysaccharide materials bearing at least one substituent group as described in i) per saccharide unit. The present invention facilitates the creation of finely dispersed liquid organic phase oil drops containing an oil soluble PUM, without the need of an auxiliary solvent, without the need to add high levels of the hydrophilic colloid and without the need to use high homogenizing temperatures. Further, the present invention facilitates the preparation of equally fine particle dispersions when the level of permanent solvent has been reduced.
