Abstract: A color diffusion transfer photographic element is disclosed. The element provides a transferred dye image in a mordant layer and includes a compound having recurrent units represented by the general formula (I): ##STR1## the substituents within the general formula (I) are defined within the specification. By utilizing the compound the images produced having improved preservability having specific improvements with respect to the elimination of yellow stains which are formed in white areas of the images after storage for a long period of time. Furthermore, the images formed do not deteriorate at high temperatures and the use of the compound does not decrease the D.sub.max in print images.

Abstract: This invention relates to diffusion transfer processes and products wherein the transmission density of the pigmented processing composition layer is increased by employing an alkali earth metal salt to increase the light-absorbing ability of a carboxynaphthol phthalein optical filter agent within said processing composition layer. In another embodiment, a carboxyindole phthalein optical filter agent also is included in said processing composition layer, and a zinc or cadmium salt is employed to shift the spectral absorption of the carboxyindole phthalein into the green region of the visible spectrum. In a further embodiment, a calcium salt is employed in a viscous pigmented processing composition comprising a light-reflecting pigment, colloidal silica and a metal chelating agent, e.g., an alkylene polyamine polyacetic acid to stabilize the spreading characteristics of the composition.

Abstract: Photographic color developer compositions containing a primary aromatic amino color developing agent and an hydroxylamine are stabilized by incorporating therein certain polyamino stabilizing agents, such as N,N'-bis(2-hydroxybenzyl)ethylenediamine-N,N'-diacetic acid. Decomposition of the hydroxylamine, in the presence of heavy metals such as iron which act to catalyze the decomposition, and resultant formation of ammonia is effectively prevented by the presence in the developer composition of such stabilizing agents. Undesirable precipitate formation is also effectively avoided.

Abstract: An image-forming method is disclosed. The method includes providing a silver halide color photographic material and imagewise exposing that material. The exposed material is color developed in the presence of a compound capable of reacting with or adsorbing a silver halide. The material is developed within a mono-bath intensifying developing solution which includes hydrogen peroxide or a compound capable of releasing hydrogen peroxide and a color developing agent. The solution substantially excludes the presence of bromide ions and iodide ions. The compound capable of reacting with or being absorbed into silver halide is a nitrogen-containing heterocyclic compound which has been found to be very useful in the image-forming method to obtain high color density with materials containing a small amount of silver halide.

Abstract: A process of developing a color photographic material with a color developer, a diphosphonic acid and a water soluble metallic salt of magnesium, aluminum, zinc, barium or zirconium.

Abstract: A processing composition adapted for use in a silver diffusion transfer process which includes a saturated polyol containing at least 3 hydroxyl groups wherein each hydroxyl group is no more than 3 carbon atoms away from another hydroxyl group.

Abstract: Lignosulfonates are incorporated in photographic developing compositions containing an indazole antifoggant in order to prevent or retard the precipitation of the indazole. Both black-and-white developing compositions, containing such developing agents as dihydroxybenzenes and/or pyrazolidones, and color developing compositions, containing primary aromatic amino color developing agents, are effectively stabilized against precipitation of indazole antifoggants by the lignosulfonates.

Abstract: Photographic color developer compositions containing a primary aromatic amino color developing agent and an hydroxylamine are stabilized by incorporating therein a combination of sequestering agents, one of which is an aminopolyphosphonic acid compound and another of which is an aromatic polyhydroxy compound. Decomposition of the hydroxylamine, in the presence of heavy metals such as iron which act to catalyze the decomposition, and resultant formation of ammonia is effectively prevented by the presence in the developer composition of this combination of sequestering agents. Undesirable precipitate formation is also effectively avoided.

Abstract: A poly(alkyleneimine), such as poly(ethyleneimine), is incorporated in a photographic color developer composition containing a primary aromatic amino color developing agent in order to protect the developing agent against aerial oxidation. The poly(alkyleneimine) also functions to reduce tar formation and retard stain growth and provides a supplemental source of alkalinity in the color developer composition.
