Abstract: There are described photographic elements containing novel release compounds which release a blocked photographically useful group, such as a blocked development inhibitor. The blocking group is removed during processing as a result of reaction with sulfite ion contained in one of the processing baths.

Abstract: A photographic development inhibitor releasing compound comprises a releasable development inhibitor group comprising an amide group containing a carbon alpha to the amide functionality which is di- or tri-fluorinated. Such a compound is useful in photographic silver halide materials and processes to enable increased image sharpness and good interimage results.

Abstract: A photographic element is disclosed including a support bearing at least one photographic silver halide emulsion layer and at least one non-photosensitive layer between the emulsion layer and the support, wherein the non-photosensitive layer comprises at least one blocked developing agent.

Abstract: A polymeric material is provided comprising a blocked photographically useful group (PUG). The incorporated blocked photographically useful group includes a PUG and a blocking group that is capable of releasing the PUG upon processing the photographic element, wherein the blocking group(a) is capable of reacting with a dinucleophile reagent, and(b) comprises two electrophilic groups that are separated from each other by a substituted atom that enables a nucleophilic displacement reaction to occur with release of PUG upon processing the photographic element in the presence of a dinucleophile reagent, wherein the group that is less electrophilic is bonded directly or through at least one releasable timing group to the PUG.Photographic elements and emulsions including the inventive polymers, and processes for developing an image in the elements, are also provided.

Abstract: There are described color photographic elements containing novel release compounds which rapidly release a photographically useful group, such as a development inhibitor, from a timing group.

Abstract: A photographic recording material capable of accelerated development is described. The recording material comprises an image-forming coupler compound, a development inhibitor releasing compound and a compound capable of imagewise release of an electron transfer agent.

Abstract: A photographic recording material is disclosed which is capable of providing improved granularity properties without sacrifice in other desirable photographic properties. The recording material comprises an image dye-forming coupler compound, a development inhibitor releasing compound, a compound capable of imagewise release of a soluble mercaptan compound and a compound capable of imagewise release of an electron transfer agent.

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: Photographic elements intended to generate dye images containing at least one colloidal silver layer and at least one hydroquinone antistain agent have been observed to suffer from random fog spotting, which can be reduced by incorporating a catalyst for the decomposition of hydrogen peroxide. The imagewise exposed elements when photographically processed and bleached of silver produce viewable dye images.

Abstract: Benzotriazole compounds employed as development restrainer precursors are described having on one nitrogen atom an alkali-hydrolyzable, N,N-disubstituted carbamoyl group. The compounds may have the following formula: ##STR1## wherein: R.sup.1 and R.sup.2 each represent a substituted or unsubstituted alicyclic, aliphatic, aromatic or heterocyclic moiety, or may be taken together with the nitrogen to which they are attached to form a heterocyclic ring; andR.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represent hydrogen, nitro, lower alkyl, halogen, carbamoyl, sulfamoyl, RCONH-- or RSO.sub.2 NH--, wherein R is lower alkyl or aryl.

Abstract: Photographic elements, assemblages and processes for color diffusion transfer photography are described wherein certain azole compounds having at least two nitrogen atoms are employed as development restrainer precursors. Preferred azole compounds include benzotriazoles, triazoles, tetrazoles, indazoles and benzimidazoles. The azole compounds have an alkali-hydrolyzable, N,N-disubstituted carbamoyl group on one of the two nitrogen atoms.
