Abstract: A color photographic recording material containing a magenta coupler corresponding to the following formula is distinguished during chromogenic development by high sensitivity, gradation and high color density and also minimal yellow secondary density: ##STR1## In the formula, X is H or a group releasable during the color coupling reaction;R.sub.1 and R.sub.2 are Cl, Br, --CF.sub.3 ;R.sub.3 is H, Cl, Br, --CF.sub.3, --OCH.sub.3 ;R.sub.4 is alkyl;R.sub.5 is alkyl or benzyl.

Abstract: Stable, color neutral images may be produced by a short time photographic process using a color photographic recording material containing at least one silver halide emulsion layer and at least one 2-equivalent magenta coupler corresponding to formula I on a (preferably reflective) layer support. ##STR1## In the above formula, B denotes a stabilizing group,Y denotes halogen, alkoxy, alkyl, alkylsulphonyl, acylamino, alkoxycarbonyl, carbamoyl, sulphamoyl, amino, trifluoromethyl or cyano,n and o stand for 0, 1 or 2 (but not both 0),p stands for 0 or an integer .ltoreq.3-o,q stands for 0 or an integer .ltoreq.5-n, andAlk stands for alkyl which may be straight chained or branched and preferably has 1 to 22 carbon atoms and is optionally substituted, e.g. with hydroxy, alkoxy, aroxy or alkoxycarbonyl.

Abstract: Dye images of high color yield and high gradation are obtained with a color photographic recording material containing 2-equivalent yellow couplers corresponding to formula I, particularly in modern rapid processing methods or in developers free from benzyl alcohol. ##STR1## R.sup.1, R.sup.2 (same or different) represent hydrogen, alkyl or halogen; R.sup.3 represents alkoxyalkyl or an alkyl radical substituted by a heterocyclic group containing at least one oxygen atom;R.sup.4 represents alkyl or aryl;R.sup.5 represents halogen or alkoxy;R.sup.6 represents hydrogen, alkoxy, amino, acylamino or carbamoyl;represents alkoxy, acylamino, carbalkoxy, carbamoyl or sulfamoyl.

Abstract: The stability to light of images produced from magenta couplers is improved by a combination of a hydroquinone and an indole.

Abstract: Compounds having a structure corresponding to the following formula. ##STR1## wherein G represents OH or a precursor group which is unstable to alkali,X represents a substituent which cannot be split off,Y represents --O--alkyl, --SO.sub.2 --NR.sup.1 --R.sup.2, --CO--NR.sup.1 --R.sup.2, --NR.sup.1 --CO--R.sup.3, or --NR.sup.1 --SO.sub.2 --R.sup.3,R.sup.1 represents H or alkyl,R.sup.2 represents alkyl, aralkyl or aryl,R.sup.3 represents alkoxy, aroxy, alkylamino, arylamino or R.sup.2,Z represents H, alkyl, alkoxy, halogen or acylamino andn represents 1 or 2are suitable for improving the stability to light of image dyes produced from photographic couplers, in particular yellow couplers.

Abstract: New triazoles of the formula ##STR1## are suitable stabilizing agents in photographic materials.

Abstract: An image receptor element for the dye diffusion transfer process contains an image-receiving layer, which has increasing dye absorption capacity with increasing distance from the light-sensitive layers. Such an image-receiving layer may be obtained by use of mordants in concentrations which increase with increasing distance from the light-sensitive layers or by use of at least two mordants of different dye absorption capacity, the mordant of higher dye absorption capacity being arranged in a partial layer of the image-receiving layer further away from the light-sensitive layers. Such image receptor elements provide higher dye densities with lower total concentrations of mordants.

Abstract: Propyne compounds, which are capable of stabilizing photographic materials against fog, color fog and flattening of the gradation are disclosed. They may be added to emulsion layers and to processing baths.

Abstract: A photographic material for the production of an image in a dry process by forming a vesicle image upon the decomposition of a peroxide compound at image nuclei of silver by providing a layer containing a silver salt which forms upon exposure to light, in imagewise distribution, image nuclei. The silver salt has a grain size of less than 0.3 .mu.m and is present in the layer in an amount of from 1-500 mg/m.sup.2.
