Claims
- 1. A photographic film product which comprises a support carrying a cyan dye developer layer in association with a red sensitive gelatino silver halide emulsion layer, a magenta dye developer layer comprising a compound which is represented by the structural formula ##STR29## wherein R.sub.1 is CH.sub.3 or ##STR30## m, n and p may be the same or different and each is an integer of from 1 to 5 in association with a green sensitive gelatino silver halide emulsion layer and a yellow dye developer layer in association with a blue sensitive gelatino silver halide emulsion layer.
- 2. A film product as defined in claim 1 wherein R.sub.1 is CH.sub.3.
- 3. A film product as defined in claim 2 wherein m, n and p are each 3.
- 4. A film product as defined in claim 1 wherein m, n and p are each 3.
- 5. A photographic film unit comprising a first support and a second support, at least one of said supports being transparent; a plurality of layers including a red sensitive gelatino silver halide emulsion layer associated with a cyan dye developer layer, a green sensitive gelatino silver halide emulsion layer associated with a magenta dye developer layer, and a blue sensitive gelatino silver halide emulsion layer associated with a yellow dye developer layer carried on one of said supports; an image receiving layer carried on one of said supports; a rupturable container releasably holding a processing composition adapted, when distributed between a pair of predetermined layers carried by said supports, to develop said silver halide emulsion layers and provide a diffusion transfer image in said image receiving layer; means providing a white light-reflecting layer between said image receiving layer and said silver halide emulsion layers to mask said silver halide emulsion layers after development thereof and to provide a white background for a diffusion transfer image formed in said image receiving layer, said diffusion transfer image being viewable through said transparent support; said supports and the layers carried thereon being held in fixed relationship with said silver halide emulsion layers being photoexposable through a transparent support, said magenta dye developer layer comprising a compound which is represented by the structural formula: ##STR31## wherein R.sub.1 is CH.sub.3 or ##STR32## m, n and p may be the same or different and each is an integer of from 1 to 5.
- 6. A film unit as defined in claim 5 wherein said image-receiving layer is carried by said transparent support, said processing composition includes a white pigment and said rupturable container is so positioned as to distribute its contents between said image receiving layer and said silver halide emulsion layers.
- 7. A film unit as defined in claim 5 wherein both said supports are transparent, said image-receiving layer and said silver halide emulsion layers are carried by the same support with a layer of white pigment therebetween and said rupturable container is so positioned as to distribute its contents between said silver halide emulsion layers and the transparent support through which photoexposure is effected.
- 8. A film unit as defined in claim 5 wherein R.sub.1 is CH.sub.3.
- 9. A film unit as defined in claim 8 wherein m, n and p are each 3.
- 10. A film unit as defined in claim 5 wherein m, n and p are each 3.
- 11. A multicolor diffusion transfer photographic process which comprises imagewise exposing a photosensitive element comprising a blue sensitive gelatino silver halide emulsion layer having a yellow dye developer layer associated therewith, a green sensitive gelatino silver halide emulsion layer having a magenta dye developer layer associated therewith and a red-sensitive gelatino silver halide emulsion layer having a cyan dye developer layer associated therewith and applying an aqueous alkaline processing composition to said exposed photosensitive element to effect development and to form an imagewise distribution of unoxidized dye developer in undeveloped areas of each of said silver halide emulsions as a function of said development, said process including the step of transferring at least a portion of said imagewise distributions of unoxidized dye developers to an image receiving layer in superposed relationship therewith to thereby provide a multicolor diffusion transfer image, said magenta dye developer layer including a dye developer as defined in claim 1.
- 12. The process as defined in claim 10 wherein R.sub.1 is CH.sub.3.
- 13. A process as defined in claim 12 wherein m, n and p are each 3.
- 14. The process as defined in claim 11 wherein m, n and p are each 3.
- 15. A film product as defined in claim 1 wherein R.sub.1 is ##STR33##
- 16. A film product as defined in claim 15 wherein m, n and p are each 3.
- 17. A film unit as defined in claim 5 wherein R.sub.1 is ##STR34##
- 18. A film unit as defined in claim 17 wherein m, n and p are each 3.
- 19. A process as defined in claim 11 wherein R.sub.1 is ##STR35##
- 20. A process as defined in claim 19 wherein m, n and p are each 3.
