Color photographic silver halide material

The present invention relates to new yellow couplers of formula (I) for colour photographic materials

Acetanilide couplers

The present invention relates to a color photographic recording material which contains, in at least one layer between the substrate and light-sensitive emulsion layer situated nearest to the substrate, a compound of formula (I)

Color photographic recording material

A colour photographic material having a yellow filter layer containing at least one decolourisable dye or dye to be able to be rinsed out of the material of the formula (I) ##STR1## in which R.sub.1 and R.sub.2 mutually independently mean a substituted or unsubstituted alkyl group,

A colour photographic recording material having at least one red-sensitive silver halide emulsion layer which is associated with a cyan coupler, at least one green-sensitive silver halide emulsion layer which is associated with a magenta coupler, at least one blue-sensitive silver halide emulsion layer which is associated with a yellow coupler contains in at least one green-sensitive silver halide emulsion layer a 2-equivalent pyrazolone coupler and in a photosensitive or non-photosensitive layer a white coupler of the formula (I) ##STR1## in which X.sup.1 means an acyl residue derived from an aliphatic, cycloaliphatic or aromatic carboxylic or sulphonic acid, a carbonic acid semi-ester or a carbamic acid,

Color photographic recording material having a 2-equivalent magenta

A colour photographic silver halide material which contains in at least one layer at least one compound of the general formula (I) ##STR1## in which R.sub.1 means hydrogen, alkyl or acyl,

A color photographic recording material comprises in a yellow filter layer at least one dye of one of the formulae I and II ##STR1## in which R.sup.1, R.sup.3 and R.sup.5 (mutually independently) mean alkyl, cycloalkyl or aryl;

Color photographic recording material having a yellow filter layer which

A colour photographic silver halide material with a support, at least one silver halide emulsion layer and at least one non-light sensitive layer applied thereto, wherein the silver halide emulsion layer contains at least one colour coupler, and wherein the silver halide emulsion layer or the non-light sensitive layer contains a compound of the formula (I) ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 mean hydrogen or an organic residue and

A color photographic silver halide material with a support and at least one silver halide emulsion layer applied thereto which contains at least one 2-equivalent pyrazolone magenta coupler of the formula (I) ##STR1## with the substituents having the meanings stated in the specification and at least one amine which contains repeat units of the formulae (II) or (III) ##STR2## with the substituents having the meanings stated in the specification, is distinguished by reduced fogging and color spotting during storage.

A bleaching bath for processing of a color photographic silver halide material which contains the ferric complex of alaninediacetic acid as the bleaching agent and in a dye-stabilizing amount a formaldehyde precursor of the formula ##STR1## wherein X and Y denote the residual atoms of a hetero aromatic 5- or 6-membered ring, yields color photographic images with excellent dye-stabilizing. In the atmosphere above the stabilizing bath no formaldehyde is detectable.

Bleaching bath

Azo dye salts corresponding to formula I are suitable as masking couplers. ##STR1## In Formula I, A denotes an optionally substituted aryl group;

Azo dye salts useful as masking couplers and preparation thereof

Color photographic recording material containing as cyan correction dyes, azomethine dyes corresponding to the general formula IV or V ##STR1## is distinguished from materials containing the cyan correction dyes hitherto used by its increased stability of latent image nuclei when stored under tropical conditions (35.degree. C. at 90% relative humidity). In formulae IV and V,

Colored cyan couplers corresponding to formula II are eminently suitable for masking the yellow secondary density of cyan dyes. The reproduction of blues and yellows is thus improved. The colored cyan couplers of formula II are preferably used together with phenolic cyan couplers bearing a phenylureido group in the 2-position and an acylamino group with a ballast group in the 5-position ##STR1## In formula II: CC represents a cyan coupler group to the coupling position of which L is attached;

Color photographic recording material containing new colored cyan

Using a color photographic negative recording material which contains a most sensitive, a medium-sensitive and a least sensitive silver halide part layer for recording light from at least one of the spectral ranges of red, green and blue, at least one of the two more sensitive part layers containing a DIR coupler and the most sensitive partial layer and the least sensitive part layer containing a color coupler which couples faster than the color coupler in the medium-sensitive part layer by a factor of at least 1.5, the sharpness can be improved without impairing the color grain.

Color photographic negative recording material

A photographic recording material contains a stabilizer in polymeric form corresponding to the following formula I ##STR1## wherein the substituents have the meanings stated in the description.
