Abstract: A photographic recording material. On a support are provided a silver emulsion halide layer and a photographic layer. The photographic layer contains an indole compound represented by the general formula (I): ##STR1## wherein PUG represents a photographically useful group, Ball represents an organic group which has enough molecular weight and/or disposition to render the compound non-diffusible during processing of the photographic recording material with an alkaline medium and wherein the Ball contains a nitrogen atom which is directly attached to the 5th or 6th position of the indole ring. R.sub.1 represents a halogen atom or a monovalent organic group. R.sub.2 represents a hydrogen atom or a low molecular group attached, through a carbon atom, to the 2nd position of the indole ring. "m" represents an integer of zero to 3.

Abstract: A process for forming a cyan dye image by using a novel photographic 2-equivalent cyan coupler which is characterized by having a splitt-off group of the below-indicated general formula at the active position of the cyan coupler so that the oxy portion is present on the side of the active position: ##STR1## wherein R.sub.1 and R.sub.2 stand for a hydrogen atom or an organic group, provided at least one of R.sub.1 and R.sub.2 should be an organic group, is disclosed.

Abstract: A novel color diffusion transfer photographic element is disclosed which is characterized as having a photosensitive element containing a compound represented by the formula ##STR1## wherein A represents oxygen or a group of the formula .dbd.NR (in which R represents hydroxyl or an amino group); X represents hydrogen or halogen; Z represents a group of nonmetallic atoms necessary to form a first ring and being a 5 to 7-membered nonaromatic hydrocarbon ring which may be fused with a second ring, at least one of said first ring and said second ring having one or more substituents wherein at least one of said substituents is a ballast group which renders said compound nondiffusible during processing with said solution; J represents a divalent group; D represents a dye moiety or a dye precursor moiety; and n represents zero or 1.

Abstract: Cyan couplers of the 2-equivalent type having the formula ##STR1## wherein C.sub.p, R.sub.1 -R.sub.6, Z, n, p and q are herein defined are described. These couplers are useful in photography, and photographic materials and developers incorporating these couplers are also described.

Abstract: Color developers represented by the following general formula are useful as color developing agents: ##STR1## R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are defined herein.

Abstract: Cyan couplers of the 2-equivalent type, useful in photography are described. These compounds are characterized in that they have at least one divalent group of the formula, --OCH.sub.2 CO--, in the molecule with a split-off group at the methoxy site of said divalent radical. Photographic materials and color developers incorporating these couplers are also described.
