A photographic acylacetanilide yellow coupler having at the acyl or anilide portion thereof a moiety represented by --X--Y--Z where X represents --NHCO-- or --CONH-- radical, Y represents a divalent organic radical, Z represents ##STR1## wherein R.sub.1 is an alkyl or aryl radical, and a color photographic material containing an acylacetanilide yellow coupler.

Silver halide color photographic material containing yellow coupler

Process for forming yellow dye images in silver halide photographic material using 2-equivalent .alpha.-pivaloyl acetanilide couplers having at the 5-position a ballasting sulfonyl amido group.

Process for forming dye images

A process for forming a photographic magenta dye image is disclosed which requires contacting exposed silver halide with a color developing agent in the presence of a particular class of 2-equivalent magenta couplers.

Process for forming a photographic magenta dye image

A method for adding oil-soluble photographic addenda in the form of their solution in a high boiling organic solvent to a hydrophilic colloidal solution for forming a layer of a light-sensitive silver halide photographic material in the homogeneously dispersed state, is described.

Method for the addition of photographic addenda

The present invention relates to a process for forming photographic images using a 2-equivalent magenta coupler position a radical of the following general formula:

A cyan coupler of the formula A -- NHCO(CF.sub.2 CF.sub.2).sub.n H wherein A is a phenolic or naphtholic cyan coupler residue and n is a positive integer of 1 to 7, incorporated in a light-sensitive silver halide photographic material produces a cyan dye photographic image which is favorable in light absorption characteristics and excellent in fastness when the coupler is developed with an aromatic primary amine type developing agent.
