Abstract: A polymeric latex to load photographically useful compounds into photographic elements comprises, as a dispersed phase, fine particles of a hydrophobic polymer which, for at least 70% of its weight, comprises:(a) repeating units derived from an ethylenic monomer containing a sulfonic or sulfonate group which monomer is capable of forming hydrophilic homopolymers, said units comprising 0.5 to 1.5% by weight of said hydrophobic polymer,(b) repeating units derived from an N-3-oxo-alkyl-substituted acrylamide, said units comprising from 5 to 25% by weight of said hydrophobic polymer, and(c) repeating units derived from acrylic acid ester monomers having a TG lower than 0.degree. C., said units comprising at least 43.5% by weight of said hydrophobic polymer,the remaining polymer weight percentage, from zero to 30%, being formed by repeating units derived from inert monomers and/or cross-linking monomers.

Abstract: 3-Aminoallylidenemalononitrile compounds corresponding to the formula: ##STR1## wherein R.sub.1 is a short alkyl chain having 1 to 3 carbon atoms and R is a substituted or unsubstituted long alkyl chain greater than 10 carbon atoms, are useful in photography for absorbing ultraviolet radiations in the range from 360 to 400 nm, with no undesired absorption near 420 nm, when introduced in a photographic gelatin layer.

Abstract: Antistatic protection can be provided to a substrate by providing two coatings or layers to the substrate. The first layer is a blend of two different polymers or copolymers that crosslink within the coating and the second layer is a subbing layer. This coated substrate is particularly useful for photographic media.

Abstract: UV-sensitive direct positive silver halide photographic elements for duplicating processes which can be safely handled under white light, said elements comprising a support base, a hydrophilic colloidal silver halide emulsion layer comprising fogged silver halide grains, and one or more hydrophilic colloidal layers, wherein said silver halide emulsion is reactively associated with a water-removable UV-absorbing compound having at least 80% of the absorption in the range from 350 to 400 .mu.m.

Abstract: A color image, wherein granularity is reduced under conditions allowing any sharpness loss to be kept under control, is obtained by image-wise exposing and developing in an alkaline water solution containing a color developer a silver halide color photographic element comprising a support base and at least a silver halide emulsion layer containing dispersed a non-diffusing hydrophobic coupler which upon reactiong with an oxidized developing agent forms a non-diffusing dye, characterized by the fact that said emulsion contains dispersed therein oil droplets, said droplets containing said non-diffusing coupler dissolved therein, and furthermore polymer particles in a quantity sufficient to obtain controlled smearing of the image-forming dye.

Abstract: A photosensitive silver halide material for obtaining black and white half-tone dot or line images comprises a fine grain and high-chloride silver halide emulsion reactively associated with an aqueous latex of a hydrophobic vinyl addition polymer in combination with a stabilizer selected from the group consisting of 4-hydroxy-1,3,3a,7-tetrazaindenes, benzotriazoles and benzimidazoles. The silver halide emulsion has an average grain size lower than or equal to 0.20 micron with at least 60% of its molar halide content consisting of chloride ions.The material allows high-contrast and high resolving power images to be obtained.The material has a good developability in photographic processings and this reduces the development times and increases productivity.

Abstract: 3-Aminoallylidenemalononitrile is useful for absorbing ultraviolet radiation near 400 nm, with no absorption near 420 nm, when directly dispersed in a photographic gelatin layer.

Abstract: A matt surface can be provided on a photographic material comprising a support base, one or more light-sensitive gelatin silver halide emulsion layers and an outer non-light-sensitive gelatin layer coated on said layers if discrete particles, insoluble in water and substantially soluble in aqueous alkaline medium, of a carboxyl group containing copolymer are introduced into said outer layer. The particles, of a diameter between 0.5 and 4 micron, are introduced into the coating composition of the outer layer as a dispersion of a methacrylic acid and ethylmethacrylate copolymer containing 20 to 50 percent by weight of methacrylic acid, which dispersion is obtained by dispersing in an aqueous solution of a hydrophilic colloid a solution of said copolymer in ethylacetate or water-including ethylacetate.

Abstract: It is generally undesirable to have surfaces on photographic elements which are highly reflective and therefore reduce the attractiveness of the image. One of the traditional means of correcting this reflectance is to coat the developed film or print with an anti-reflective coating or to place a glass cover over the imaged photographic element where the glass itself has an anti-reflective surface.According to the present invention, an anti-reflective surface may be provided within the photographic element itself by including within a top coat gelatin layer a combination of a first water-soluble soft matting agent incompatible with gelatin and a second water-insoluble soft matting agent.

Abstract: The present invention refers to a photographic material including in one of its layers a polymeric product having an aminoallylidenemalononitrile ultraviolet absorber unit which can be introduced into a photographic layer by aqueous solutions, with the method according to this invention, of including said aminoallylidenemalononitrile unit in an allyl monomer and then copolymerizing it with an ethylenically unsaturated monomer in order to obtain said polymeric product to be added to the layer forming composition. This invention is of particular industrial interest in the field of color photographic materials.
