Color diffusion transfer photographic light-sensitive material for forming both positive transfer dye images and negative dye images

A color photographic light-sensitive material which comprises a transparent support having thereon at least three silver halide emulsion layer units, each of which is sensitive to a different wavelength region of light and capable of simultaneously providing, as a result of exposure and development, both a diffusable dye with a positive image distribution and non-diffusible dye with a negative image distribution, these units including

• I. a blue sensitive emulsion layer unit comprising (1) a hydrophilic collodial layer containing a ballasted yellow coupler capable of reacting with an oxidation product of an aromatic primary amine color developing agent to form a diffusible yellow dye, and a spontaneously developable, slightly soluble silver salt dispersion, (2) a first negative type blue-sensitive silver halide emulsion layer provided adjacent said colloidal layer (1) and containing a ballasted compound capable of reacting with an oxidation product of an aromatic primary amine color developing agent to release a diffusible development inhibitor inhibiting the development of said silver salt in the above described colloidal layer (1), and (3) a second negative type blue-sensitive silver halide emulsion layer containing a ballasted yellow coupler capable of reacting with an oxidation product of an aromatic primary amine color developing agent to release a nondiffusible yellow dye image having a negative gradation suitable as an original for color printing in cooperation with said silver halide emulsion layer (2);
• Ii. a green-sensitive emulsion layer unit comprising (1) a hydrophilic colloidal layer containing a ballasted magenta coupler capable of reacting with an oxidation product of an aromatic primary amine color developing agent to form a diffusible dye, and a spontaneously developable, slightly soluble silver salt dispersion, (2) a first negative type green-sensitive silver halide emulsion layer provided adjacent said colloidal layer (1) and containing a ballasted compound capable of reacting with an oxidation product of an aromatic primary amine color developing agent to release a diffusible development inhibitor inhibiting the development of said silver salt in the above described colloidal layer (1), and (3) a second negative type green-sensitive silver halide emulsion layer containing a ballasted magenta coupler capable of reacting with an oxidation product of an aromatic primary amine color developing agent to release a non-diffusible magenta dye and providing a dye image having a negative gradation suitable as an original for color printing in cooperation with said silver halide emulsion layer (2);
• and
• Iii. a red-sensitive emulsion layer unit comprising (1) a hydrophilic colloidal layer containing a ballasted cyan coupler capable of reacting with an oxidation product of an aromatic primary amine color developing agent to form a diffusible dye, and a spontaneously developable, slightly soluble silver salt dispersion, (2) a first negative type red-sensitive silver halide emulsion layer provided adjacent said colloidal layer (1) and containing a ballasted compound capable of reacting with an oxidation product of an aromatic primary amine color developing agent to release a diffusible development inhibitor inhibiting the development of said silver salt in the above described colloidal layer (1), and (3) a second negative type red-sensitive silver halide emulsion layer containing a ballasted cyan coupler capable of reacting with an oxidation product of an aromatic primary amine color developing agent to release a non-diffusible cyan dye and providing a cyan image having a negative gradation suitable as an original for color printing in cooperation with said silver halide emulsion layer (2).
