Abstract: A photographic element comprising a support, a layer containing certain photographically useful and/or active fragments and a layer containing a dye mordant composition comprising a polymer having recurring units of the formula selected from the group consisting of: ##STR1## wherein: R.sup.2 is hydrogen or alkyl;R.sup.1 is hydrogen, alkyl or aryl;L is a linking group;W is an electron-withdrawing group;X is a leaving group; andn is 0 or 1.The polymeric mordants covalently bond with dyes or dye precursors and are especially useful in diffusion transfer processes.

Abstract: A .beta.-eliminating graft copolymer useful as a diffusion control layer in film units adapted for diffusion transfer processes is disclosed.

Abstract: A method for dispersing an oil-soluble photographic additive which comprises dissolving the additive in an organic solvent and dispersing the resulting solution of the photographic additive in water or a hydrophilic colloid composition in the presence of a surface active polymer comprising (a) a homopolymer of units represented by the formula (I): ##STR1## wherein R is an aliphatic hydrocarbon group having 4 to 22 carbon atoms; m.sub.1 and m.sub.2 each is 0 or 1; B is --O-- or --NH--; A is a divalent aliphatic group having 1 to 50 carbon atoms; and M is a hydrogen atom or a cation group capable of forming a salt with a sulfonic acid group, or (b) a copolymer containing at least 5 mol% of units represented by the formula (I) above and the balance of divalent units copolymerizable therewith and comprising at least one of a benzene ring having a methylene group attached thereto and a naphthalene ring having a methylene group attached thereto.

Abstract: Useful non-diffusible dye-giving compounds for the photographic dye diffusion transfer process are dye sulfonamides derived from enolamines or endiamines or tautomers thereof. The dye-giving compounds are oxidized by developer oxidation products and subsequently split under the conditions of alkaline development to release diffusible dyes. The compounds are of the following formula ##STR1## in which X is a dye moiety and R.sub.1, R.sub.2 and R.sub.3 have meanings given hereinafter.

Abstract: Photographic elements, film units and processes are described wherein N-alkyl- or N-aryl-benzisoxazolones are used to scavenge oxidized electron transfer agents in negative-working, color image transfer elements. The scavenger precursor compounds can be located in an emulsion layer or in a dye image-providing material layer, and in a ballasted form can be located in an interlayer.

Abstract: A photographic light-sensitive material comprising a support having thereon at least one silver halide photographic emulsion layer and containing an emulsified dispersion comprising an organic solvent and an organic solvent gelling agent in at least one hydrophilic colloid layer thereof, a process for producing an emulsified dispersion using an organic solvent gelling agent and a process for stabilizing a photographic light-sensitive material containing an emulsion of an oleophilic photographic additive in a hydrophilic colloid layer thereof using an organic solvent gelling agent.

Abstract: Undesired color fog obtained on color development of a color photographic material with a primary aromatic amino color developing agent may be reduced when the development is carried out in the presence of an antifogging agent (antistaining agent) of the formula ##STR1## in which R.sup.1 is an acyl group and R.sup.2 and R.sub.3 are (same or different) hydrogen, alkyl, halogen, sulfo or carboxyl.The antistaining agent is preferable incorporated in non-diffusible form in one or more of the layers of the photographic material.

Abstract: Improved sensitivity and improved interimage effects are obtained in a multilayer color-photographic recording material having two red-sensitive, two green-sensitive and a blue-sensitive silver halide emulsion layer as well as a yellow filter layer, the more sensitive red-sensitive and the more sensitive green-sensitive layers forming a comparatively more sensitive layer unit arranged further away from the support than each of the less sensitive green-sensitive and the less sensitive red-sensitive layer but nearer to the support than the yellow filter layer underneath the blue-sensitive layer; an additional chloride-containing silver halide emulsion layer of comparatively low sensitivity containing a non-diffusible DIR compound of low reactivity is arranged within the comparatively more sensitive layer unit between the red-sensitive and the green-sensitive layers.
