    摘要： A black & white paper with variable gradation containing a silver chloride-bromide emulsion, which is divided into at least three portions, one of which is sensitised with a blue sensitiser and two further portions are sensitised both with differing quantities of blue sensitiser and with differing quantities of a green sensitiser, wherein the blue sensitiser is of the formula (I) and the green sensitiser is of the formula (II) ##STR1## in which R.sub.1 to R.sub.8, X.sup.(-) and m have the meaning stated in the specification, is distinguished by an extended gradation range.

    摘要： Process for the production of color images by the color photographic dye diffusion process in which development is brought about by heat and water. The combination of antifoggants added to the light-sensitive material, in particular the combination of compounds of formulae I and II, produces a marked improvement in storage stability and constancy of sensitivity with good D.sub.min /D.sub.max ratios. ##STR1## R.sup.1 denotes hydrogen, alkyl with up to 6 carbon atoms, hydroxy, halogen, alkoxy or substituents which together form a condensed benzene ring, and in formula II below: ##STR2## R.sup.2 denotes a group which can be split off in the process of development of the material andR.sup.3 denotes hydrogen, halogen, alkyl with up to 4 carbon atoms, alkoxy, carboxy, carbalkoxy, carbonamido or sulphonamido.

    摘要： Color prints are prepared in the form of retained images by the dye diffusion transfer process using a photographic recording material comprising in that order a transparent layer support, a light-sensitive element containing at least one silver halide emulsion layer and a non-diffusing color-providing compound associated thereto, a light-reflecting opaque layer and a mordant layer. The recording material is subjected to imagewise exposure through the transparent layer support. During development a colored moiety is released from the color-providing compound in imagewise distribution and transferred to the mordant layer. Silver and silver halide is removed by bleaching and fixing. The colored color-providing compounds retained in the light-sensitive element in imagewise distribution complementary to the transferred colored moiety form the color image visible through the transparent layer support against the light-reflecting background of the opaque layer. The mordant layer prevents contamination of the developer by diffusible dyes.
