Abstract: A process for the treatment of a photographic material particularly a high speed photographic material, comprising an emulsion containing silver halide grains the treatment being to reduce the sensitivity of the material to ionizing radiation comprises prior to exposure, subjecting the material to a treatment that reduces the surface image dispersity so that fewer centers develop on each grain. The process may involve subjecting the photographic emulsion to physical pressure to deform the grains to introduce internal trapping centers for latent image formation so that a proportion of the latent image can be formed within the grains rather than on the grain surface.

Abstract: A process of transferring a photographic image to a stone surface, such as slate tile, provides for the use of a gelatin subbing solution in a step of preparing the stone surface for the receipt of the image. Additional steps include application of polyacrylic coating and concrete staining material to the surface prior to exposing the surface to the gelatin subbing solution, and using conventional photo developing compounds for permanently affixing a transferred image to the stone surface. Mixing gelatin, chrome alum and water makes the gelatin subbing solution. For an “antique” look, the photograph can be exposed to a sulfide sepia toner prior to transfer of the image to the stone surface.

Abstract: It is important to control the temperature during the development stage of a photographic process in order to maximize the efficiency thereof. This is a particular problem when photographic materials are processed in high throughput processors which operate with reduced volume chemistry as these material have a tendency to cool the developer solution if not at the correct temperature. Described herein is a method for improving the temperature stability of the material to be processed by heating it before processing. The material is passed through a conditioning chamber where it is heated to the desired processing temperature prior to entering the development stage of a processor.

Abstract: Layers containing proteinaceous binders, in particular gelatin layers of the kind used, for example, in photographic recording materials, are hardened by means of an instant hardener by casting a hardening system composed of at least two layers over the layer of binder, the lower of these two layers containing the instant hardener while the upper layer, which may be applied together with or immediately after the lower layer, contains a protein-containing binder but no hardener. The hardened layers have improved surface properties (wet scratch resistance, antifriction properties).

Abstract: A process for forming an anti-halation layer on the surface of a polyester photographic film support comprises the steps of (1) subjecting the surface to an activation treatment such as, for example, corona discharge treatment; (2) coating the activated surface with a composition comprising an anti-halation agent, such as carbon black, and an alkali-soluble polymeric binder, such as cellulose acetate hexahydrophthlate, dispersed in a liquid organic medium; and (3) drying the coating to thereby form an anti-halation layer which is strongly adherent to the polyester film suport yet is readily removable by an alkaline photographic processing solution.

Abstract: A method of locally providing metal on a surface of a substrate, in which the substrate is provided at the surface with an electrocatalythic image. The surface is then brought into contact with an electroless metal-plating solution. The electrocatalythic image is capable of binding metal to it from the metal-plating solution. Due to the fact that the image is brought into contact with the metal-plating solutin, the image is gradually strengthened with metal from the solution. With images smaller than 10 .mu.m, this strengthening is prevented, however, due to the fact that oxygen is present in the solution. Because oxygen is reduced, a reduction of metal ions in the solution cannot occur, as a result of which no metal deposition takes place on the image. According to the invention, the reduction of oxygen in the solution is counteracted at least relatively so that also in the case of images smaller than 10 .mu.m metal ions are reduced without hindrance to the metal, which is then deposited on the image.

Recreational, professional and military photo duplication techniques are greatly improved by the present invention.

Abstract: Producing metal images or patterns on and/or below the surface of a substrate material comprising a semiconducting light-sensitive compound, such as titanium dioxide or zinc oxide which after exposure of a metal compound releases this metal in the form of nuclei. Exposure takes place in the solution of the metal compound by means of a moving beam of laser light whereby the nuclei pattern is directly "written". Thereafter, the nuclei image is intensified in known manner to produce a visible image or a conductive pattern, for example by means of an electroless plating solution. Use: the recording of information as well as the production of printed circuit boards.

Abstract: For the recording of local boundary-layer flow-line directions in liquid media by means of a photographic layer,(a) small reagent depots or deposits, with a volume of about 0.2 mm.sup.3, of a water-soluble substance reactive to silver ions ("chemical flow line indicators") are applied in raster fashion to the surface which is to be exposed to the flow and which surface is previously coated with a dry or swelled photographic sheet film,(b) the reagent deposits are covered with an inert layer which is soluble in the liquid flow medium,(c) the surface so prepared is exposed to the flow of an aqueous flow medium, and(d) the film is developed according to conventional means.The reagent deposits, which may be present as a paste, can contain a precipitation agent for silver ions. The deposits can be applied as a dot raster to the surface which is to be exposed to the flow (and which is coated with a photographic film) by means of screen printing or by means of a hole raster template.

Abstract: The disclosed method relates to a method for recording flow boundary layers in liquid media by photochemical means. According to the invention, surfaces which can be developed in a plane and to which a photographic film sheet is cemented are exposed under steady-state conditions to the flow of a liquid medium containing a dissolved agent reacting with the photo gelatin layer. The liquid medium may contain agents furnishing HS-ions or agents capable of dissolving silver halide or reducing silver halide. If a photographic film sheet is used, the silver ions of which are reduced to silver, the flow exposure is performed with an agent having oxidizing and dissolving action. With the method disclosed, half-tone photograms of flow boundary layers in liquids can be recorded.

Abstract: The invention relates to a method for making visible by photochemical means residual moisture distributions in photographic wet film layers subjected to a gas flow. According to the invention, a film diffusely pre-exposed is immersed in an aqueous swelling agent solution which contains either (a) a reducing agent or (b) an alkali. After being exposed to the air stream, the invisible residual moisture profile is immersed in an alcoholic solution of either (a) an alkali or (b) a reducing agent. The half-tone image produced serves for determining stationary local boundary layer thickness distributions, wall shearing stresses, material transfer coefficients and heat transfer coefficients.

Abstract: Stationary heat transfer coefficient fields are made visible by applying a swelled photographic film (original wet film) in daylight to the article to be exposed to the flow. The wet film obtained after it is exposed to a gas flow and removed from the article, is squeezed onto an unexposed dry photographic film. The separated wet copy (latent image) is seeded with reactive gas (H.sub.2 S) to make the moisture profile visible, and is developed into a wet-copy photogram (black-and-white picture), the sharp contours of which (line equidensities, isohumids) can optionally be translated into colors, corresponding to the stationary mass transfer distribution, and with which definite heat transfer coefficients can thereby be correlated.

Abstract: For developing residual-moisture photographs according to the wet-film technique, a pre-treatment with a first solution of about 5% ethanolic NaOH is performed first at about 13.degree. C. After the alkali exchange, the exposed film passes through a bath at a bath temperature of 50.degree. C. with a hydroquinone-containing photographic developer. This "Two-bath wet developing method" takes place in daylight. The developed, fixed, rinsed and dried film can be evaluated directly.
