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 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.

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： 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.

摘要： 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.
