Abstract: Photographic elements, processes for forming images in photographic elements and new compounds are disclosed. Generally, the invention relates to improved immobile compounds which can be used to provide positive images from negative recording-developing photographic materials such as negative silver halide emulsions. The compounds contain a photographically useful group such as a dye or dye precursor and are capable of releasing said photographically useful group under alkaline conditions, and are also capable of reaction with an oxidized silver halide developing agent before substantial release of said photographically useful group occurs, to provide a reaction product having a substantially lower rate of release of said photographically useful group.

Abstract: Non-diffusible dye-providing components which may be used in association with a silver halide emulsion layer and on development yield diffusible yellow dyes of improved light fastness are cyanalkyl aminoazo dyes of the formula ##STR1## in which A.sup.1 represents oxidizable carrier residue;D represents a heterocyclic or carbocyclic aromatic residue completing an azo dye; and1, m and n are 0 or 1 such that1+m+n=1;and r represents an integer of from 1 to 4.

Abstract: Photographic elements, film units and processes are described wherein N-alkyl- or N-aryl-benzisoxazolones are used to scavenge oxidized electron transfer agents in negative-working, color image transfer elements. The scavenger precursor compounds can be located in an emulsion layer or in a dye image-providing material layer, and in a ballasted form can be located in an interlayer.
