    摘要： 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.Such polymeric latex can be loaded with hydrophobic compounds to obtain stable coating compositions which are suitable for a uniform dispersion in a hydrophilic layer of a photographic material.

    摘要： 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.

    摘要： 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.

    摘要： 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.
