Abstract: A color photographic recording material comprising a support and at least one photosensitive silver halide emulsion layer, with which a yellow coupler of the pivaloyl or benzoyl acetanilide type dissolved in a polymeric ester of aromatic or aliphatic dicarboxylic acids is associated, is distinguished by greater color purity and better dark-fading stability.

Abstract: The invention relates to a photographic recording material comprising a layer support and, arranged thereon, at least one photosensitive silver halide emulsion layer which contains an antifogging agent corresponding to formula (I) ##STR1## in which A, R.sub.1 and R.sub.2 are as defined in the specification. The antifogging agents according to the invention reduce fogging without significantly affecting gradation and improve the staility of the photographic material in storage.

Abstract: In combination with oil formers of the alkylphenol type, 3-anilinopyrazolones show absorption maxima displaced by about 8 to 12 nm towards longer wavelengths and a blue secondary absorption further displaced towards the UV range and, hence, a reduced yellow secondary density.

Abstract: Yellow couplers corresponding to the formula ##STR1## wherein Y represents an aromatic, aliphatic or cycloaliphatic group,X represents hydrogen or a releasable group,R.sup.1 represents halogen, andR.sup.2 and R.sup.3 each represent an alkyl group having 1 to 20 carbon atoms,are readily soluble in oil formers and undergo coupling with a high color yield. They are resistant to heat and moisture and undergo color development to yield stable yellow dyes with an absorption maximum below 450 nm. They have a high absorption capacity in the near UV region and are virtually unaffected by fluctuations in the pH during processing.

Abstract: Thiocarbohydrazide derivatives act as stabilizers when processing photographic materials in the conventional black and white developers of the type used as first developer in color reversal processes. Furthermore, they can promote the development of color in the second developer in color reversal processes in such a way that a second exposure or fogging baths may be dispensed.

Abstract: Process for the preparation of silver images by imagewise exposure of a photographic material comprising at least one light-sensitive silver halide emulsion layer and treatment of the material with a developer composition, wherein the improvement comprises the development is carried out in the presence of 3-mercapto-5-(2-furyl)-1,2,4-triazole. The 3-mercapto-5-(2-furyl)-1,2,4-triazole decreases the fog during development, and when this is the first development in a black-and-white or color reversal process, increases the reversal silver or color density.
