Definitions

  • a diffusion transfer color photographic material having improved color separating power and giving trans ferred color images having improved density compris' ing a support having thereon at least two layers each containing a dye developer and at least two silver halide photographic emulsion layers, at least one of which contains a compound represented by general formula wherein Q represents an atomic group necessary for forming an unsubstituted or substituted heterocyclic ring and R represents an unsubstituted or substituted alkyl group. an unsubstituted or substituted aryl group, or a heterocyclic group.
  • the present invention is generally directed to diffusion transfer color photography and more particularly to a diffusion transfer color photographic material having multilayers containing dye developers capable of providing transferred color positive images by development.
  • the unreacted and unoxidized dye developers are mobile in a processing composition and at least a part of the imagewise-distributed dye developers is transferred to an image-receiving layer positioned in superposed relationship with the photosensitive emulsion to form positive dye images thereon.
  • a lightscnsitive material having a silver halide emulsion layer and a layer of dye developer is exposed and treated with a liquid processing composition in the dark by, for example, immersion, coating, spraying, etc.
  • the exposed light-sensitive material is brought into superposed relationship with an image receiving layer capable of mordanting the dye before, during, or after the application of the liquid processing composition.
  • the light-sensitive material contains a dye developer in a layer disposed behind the silver halide emulsion layer with respect to the incident direction of light, and a liquid processing composition is supplied between the light-sensitive ma terial and the image receiving sheet by spreading processing composition therebetween in a thin layer as the emulsion layer of the light-sensitive material is brought into a superposed relationship with the image-receiving layer of the image receiving sheet.
  • the liquid processing composition thus supplied diffuses into the emulsion layer causing the development of the developable silver halide in the emulsion layer.
  • the dye developer to be combined with the silver halide emulsion is immobilized in the developed areas as a result of development and the immobi lization is apparently due, at least in part, to a decrease in the mobility and solubility of the oxidation product of the dye developer as compared to the unoxidized dye developer.
  • the immobilization is considered to be also due, in part, to a local decrease in alkali density as a function of development.
  • the imagewise distribution of the mobile unoxidized dye developer is formed as a function of the exposure and development of the silver halide emulsion.
  • the imagewise distribution of the diffusible unoxidized dye developer is, at least in part, transferred to the image-receiving layer positioned in superposed relationship with the light sensitive material by imbibition. This transfer is clearly distinguished from the lessdiffusible oxidation type dye developer and forms a visible transfer image on the image-receiving layer.
  • the unoxidized dye developer which diffuses into the superposed image-receiving layer from the inside emulsion layer must pass through at least one other outside silver halide emulsion layer, and when the unoxidized dye developer diffused from the inside emulsion layer reaches the outside emulsion layer containing the developable silver halide it reacts with the developable silver halide grains in the outside emulsion layer and then is immobilized therein.
  • a mul tilayer-type lightsensitive material composed of a support having thereon a red-sensitive emulsion layer, a greensensitive emulsion layer and a blue-sensitive emulsion layer, in that order.
  • These silver halide emulsion layers have a cyan dye developer, a magenta dye developer, and a yellow dye developer, respectively, in layers disposed behind the silver halide emulsion layers or in the silver halide emulsion layers themselves.
  • the unoxidized cyan developer will diffuse by development and will pass through the green-sensitive emulsion layer before it reaches a superposed image-received layer.
  • the magenta dye developer has substantially finished the development of the developable greensensitive silver halide before the unoxidized cyan dye developer reaches the green-sensitive emulsion layer, no trouble will occur.
  • the cyan dye developer diffuses into the green-sensitive silver halide emulsion layer while developable silver halide which has not yet been developed is present in the emulsion layer, the cyan dye developer causes a reaction with the diffusible silver halide having a different color sensitivity without discriminating as to portions of such silver halide to be immobilized.
  • the unoxidized yellow dye developer will reach the green sensitive emulsion layer by diffusion. If a developable silver halide is present in the green-sensitive emulsion layer, the yellow dye developer will also be immobilized in the greensensitive emulsion layer as in the case of the cyan dye developer. Therefore, the transfer image obtained on the image-receiving layer will show a cyan density and yellow density somewhat lower than those actually due to the exposure.
  • a phenomenon as mentioned above appears when a multilayer type negative photographic material is developed, and it is called the entangled phenomenon" in this specification.
  • the reduction in transfer density and color separation due to the engangled phenomenon of the dye developers can be improved to some extent by using a superposed effect as defined below.
  • the superposed effect is based on the phenomenon that in the development of a multilayer photographic material for diffusion transfer color photography, the development of one photosensitive emulsion layer by a dye developer has an influence on the development of the other photosensitive emulsion layer or layers by a developer or developers, and further the density of a dye developer transferred to an image-receiving layer has substantially no relationship to the development in other emulsion layer or layers.
  • a film support was coated with a cyan dye developer, a red-sensitive emulsion, a magenta dye developer, and a green-sensitive emulsion, in that order.
  • the sample thus prepared was cut into two segments, one of which (sample I) was exposed uniformly to only green light with a middle intensity, while the other (sample H) was exposed uniformly to green light with a middle intensity as for sample l and then subjected to a wedge exposure by red light. After development, the density of the magenta dye transferred to the image-receiving layers was measured for samples l and ll.
  • Sample i showed the same magenta transfer density throughout all portions of the sample, while sample ll gave a transfer image having reduced magenta transfer density in proportion to the exposure amount of red light. This was clearly based on the occurence of the entangled phenomenon.
  • the superposed effect is the effect of preventing the reduction in ma genta transfer density and the phenomenon that the magenta transfer density becomes constant regardless of the amount of red light exposure. Accordingly, it may be concluded that if the superposed effect is too high, density increases.
  • Q represents an atomic group necessary for forming a heterocyclic ring which may be substituted
  • R represents an unsubstituted or substituted alkyl group, an unsubstituted or substituted aryl group, or a heterocyclic ring.
  • a developing inhibitor in an emulsion layer in which development is started, a developing inhibitor accumulates around the emulsion to inhibit the occurence of development during subsequent periods. Accordingly, when a dye developer which is not combined with said emulsion layer diffuses into said emulsion layer at development, the emulsion layer is essentially in such a state that the development thereof is stopped or inhibited. Furthermore, the development inhibitor diffuses imagewise into the adjacent emulsion layer and also inhibits the development of said emulsion. Therefore, unoxidized dye developer combined with the adjacent emulsion layer is released to too great of a degree, and thus a dye developer immobilized by the entangled phenomenon will be compensated for by the aforesaid dye developer in amount.
