A photographic light-sensitive element comprising a support and having thereon at least one silver halide emulsion layer containing an .alpha.-diacylamino substituted (aliphatic acyl) acetamide yellow dye forming coupler and a method for forming yellow dye images which comprises processing a silver halide photographic emulsion with an aromatic primary amino developing agent in the presence of an .alpha.-diacylamino substituted (aliphatic acyl) acetamide compound are disclosed. The coupler is an excellent two-equivalent coupler.

Photographic light sensitive element containing yellow color coupler and

A process for developing a light-sensitive material comprising a support having thereon at least one internal latent image-forming silver halide photographic emulsion layer which comprises, after imagewise exposure, developing the light-sensitive material with an alkaline solution of a developing agent in the presence of a compound represented by the formula I which is capable of selectively forming latent images in the inner portions of said silver halide upon development: ##STR1## wherein Y represents an acyl group or a cyano group and said acyl group and the 3-, 4- or 5-position of the pyridinium ring may be optionally substituted.

Process for developing a silver halide emulsion

A color photographic material suitable for processing with an alkaline solution in the presence of a developing agent is described, comprising a support and, in sequence, the following five layers: (1) a first emulsion layer containing an internal latent image forming direct reversal silver halide emulsion that is selectively sensitive to light in a first spectral region; (2) a first color material layer containing a ballasted dye releasing redox compound that provides a dye image that selectively absorbs light in the first spectral region; (3) an intermediate layer containing a ballasted reducing agent that captures an oxidized developing agent or electron transfer agent; (4) a second emulsion layer containing an internal latent image forming direct reversal silver halide emulsion that is selectively sensitive to light in a second spectral region; and (5) a second color material layer containing a ballasted dye releasing redox compound that provides a dye image that selectively absorbs light in the second spectral region. The improvement is that a surface latent image forming negative silver halide emulsion that is sensitive to light in the second spectral region is uniformly incorporated in the intermediate layer (3) so as to make uniform the distribution of oxidation of said reducing agent that is formed in the intermediate layer (3) as a result of development of the second emulsion layer.

Direct reversal photographic color material

The process of forming a dye image by developing an image-exposed silver halide photographic emulsion layer by an aromatic primary amine color developing agent in the presence of the yellow dye forming coupler shown by the general formula ##STR1## wherein R.sup.1 represents an aromatic group, R.sup.2 represents an aromatic group or a heterocyclic group, and Z represents the non-metallic atom or atoms necessary for forming a 4-membered ring, a 5-membered ring or a 6-membered ring together with ##STR2## in the above formula. A photographic element containing such a yellow-forming coupler.

Process of forming yellow photographic images

A camera which permits film units to be initially stored as a plurality of first sheets and an equal number of second sheets. In taking a photograph, a first sheet is exposed and then transferred into correctly aligned contact with a corresponding second sheet, which may constitute a subsequently sealable folder or envelope for containment of the first sheet, or a cover which is bondable to the first sheet. This transfer of a first sheet is effected entirely independently in the camera, or by a camera mechanism acting on a draw mechanism attached firmly but not fixedly to the first sheet, in this latter case the draw mechanism being detached from the first sheet immediately subsequent to transfer thereof into association with the second sheet. The semifilm unit constituted by the assembled first sheet and second sheet is then removed to the exterior of the camera to form a complete film unit in which, the first sheet and second sheet are bonded together, and, if the semi-film unit is an auto-process type film unit, simultaneous processing thereof is effected during this removal.
