Definitions
- the present invention relates to a rapid reversal developing process for obtaining color photographic images with color films or color photographic papers in a very short period of time.
- a color photographic light-sensitive material to be processed by the process of this invention is produced by applying at least one light-sensitive emulsion layer comprising a silver halide emulsion and a coupler to a support.
- a light-sensitive material includes a single-layer color photographic material which gives a colored line image and is used for display, a color photographic material for drawing which has two or three lightsensitive emulsion layers each containing a different coupler and having a ditferent spectrally sensitive region, thus giving three-colored or seven-colored line image, a light-sensitive material for scientific recording such as recording material for an oscillogram, and a light-sensitive material developed for industrial purposes.
- a light-sensitive material used for scientific researches such as for oscillogram recording or photographic recording in industrial fields is required to give images in a short period of time. Also, it is profitable that a photographic light-sensitive material for reproducing drawings can be rapidly processed. For processing such light-sensitive material rapidly, a process in which a positive image is directly obtained by reversal development is more profitable than a conventional process in which a positive image is obtained through a negative light-sensitive material by two image-forming steps. Accordingly, the development of a rapid reversal developing process for color photographic light-sensitive materials has large practical merit and also is profitable not only for industrial purposes, scientific researches, drawings, and audiovisual education but also for general color photographic light-sensitive materials.
- a color reversal photographic developing process conventionally practiced usually requires a processing time of from 30 minutes to one hour.
- the conventional process of the shortest processing time among the known high-temperature rapid processing requires a processing time of about 20 minutes, and further, it requires a large volume of water for washing, and also the processing steps are complicated.
- the complication of the conventional developing process is as follows: that is to say, in the conventional reversal color process such steps as a black-and-white development (socalled primary development), a color development, a stop, and a bleach or a bleach-fixation are inevitably employed, and it requires not only washings between the steps but also, often, such additional steps as prehardening, post-bath, and salt-bath. Consequently, the conventional color reversal process requires usually more than 10 steps. Therefore, such development is usually conducted in a developing laboratory having well-furnished equipment.
- An object of the invention is, therefore, to provide a rapid and simple color reversal photographic developing process for color photographic light-sensitive materials.
- washing steps must be omitted and also for preventing the degradation of the photographic properties of the images formed in the case of omitting the washing steps, it is necessary to prevent a processing solution from being transferred to the next processing bath carried by the photographic material or carrier therefor.
- a thin paper having a weight of less than g./m.
- a non-water-absorptive resin-coated paper which is obtained by coating a resin layer on a paper or by impregnating a paper with a resin, or a plastic film hydrogen-phosphate peracetic acid and other inorganic salts may be added thereto to provide a proper salt strength and buffering faculty.
- the bleach-stabilizing bath contains an oxidizing agent for the developed silver and a complexing agent for the silver ion. Since the former oxidizes the developed silver to silver ion and the latter converts the silver ion into a complex compound or a stable colorless compound, even if such a colorless compound is left in the image in a colorless state, it gives no trouble for practical purposes.
- the suitable oxidizing agent is a trivalent iron ethylenediamine tetraacetic acid complex salt, a ferricyanide, or potassium bichromate.
- the complexing agent sodium thiosulfate or sodium thiocyanate is used for the iron ethylenediamine tetraacetic acid complex salt and also sodium thiocyanate is used for other oxidizing agents.
- the bleach-stabilizing bath may contain a salt having a buffering action, such as sodium hydrogenphosphate. Furthermore, in the case of using a bleach-stabilizing bath containing the iron ethylenediamine tetraacetic acid complex salt, the fourth step may be omitted.
- the processing solution for the final step is an aqueous solution containing sodium sulfite, sodium hydrogenphosphate, borax, and in one case may be sodium thiosulfate, and has the action of improving the quality of the image surface, after processing, and preventing the formation of sticky surface.
- the speed for the reversal color photographic developing process is several times faster than that of a conventional rapid reversal color photographic developing process, a desired positive image is obtained in a short period of time, or within 3 minutes, or even within one minute if suitable processing conditions are selected, and, further, the process is very simple.
- a stabilization process for color photography can be applied to a reversal developing process.
- a reversal developing process has, hitherto, required final water washing for a long period of time but the inventors have succeeded in applying a stabilization process to the reversal color photographic development as the results of various investigations, whereby the final washing, which takes a long period of time and is required in a conventional reversal developing process, becomes unnecessary.
- a stabilization process has been applied to only very simple methods of either black-and-white or color photographic processing, but the inventors have succeeded in simplifying the complicated reversal color photographic processing and making the stabilization step effective for reversal color processing.
- the reversal color photographic processing can be simplified.
- a typical process for conventional reversal color photographic processing consists of -14 steps, as well as being complicated, and requires a long period of time for finishing all of the steps, whereas the steps can be reduced to 3-6 steps in accordance with the present invention.
- the minimum necessary baths in the process of this invention are a black-and-white developing bath, a color developing bath, and a bleach-stabilizing bath, that is to say, by using only the three baths, images fitting practical purposes can be produced by the process of this invention.
- additional steps may be further applied, but even if such addition steps are used, the number of the steps is at most 6, which is far less than the number of steps in a conventional process, and also each step can be finished in a shorter period of time.
- the process of this invention has particularly large advantage when it is applied to the light-sensitive materials for drawing, scientific recording, and industrial purposes, and such combinations of the process of this invention and the specific photographic light-sensitive materials are some of the main features of this invention.
- films or thin papers having low water-absorptive property are used.
- a particularly thin paper or a less water-absorptive water repellent paper is suitable.
- a translucent paper a paper coated with a polymer, such as a polyolefin, for preventing the diffusion of a processing solution, or a resin-impregnated paper is preferably used.
- silver halide emulsion compositions As the photographic emulsion to be applied to the support in this invention, various silver halide emulsion compositions, emulsion layer constructions, and sensitivities can be employed.
- silver halide composition there are employed silver chloride, silver chlorobromide, silver iodobromide, and silver chloro-iodo bromide.
- a photographic emulsion having a high specific sensitivity is used for a blue-sensitive emulsion layer and emulsions spectrally sensitized and having low specific sensitivities are employed for a green-sensitive emulsion layer and a red-sensitive emulsion layer, but if a high sensitivity is required for the light-sensitive material, a silver halide emulsion (ordinary silver iodobromide emulsion) having such a high specific sensitivity as is being used for camera photographing, may be used for each emulsion layer of the light-sensitive material and a suitable combination of a spectrol sensitization and the application of a yellow filter layer may be applied.
- one to three silver halide emulsion layers are usually applied to the support and, as occasion demands, intermediate layers and a protective layer are applied.
- a dichromatic color photographic light-sensitive material is prepared by applying to the support a bluesensitive emulsion containing a yellow coupler, an intermediate layer, a green-sensitive emulsion containing a magenta coupler and a cyan coupler, and a protective layer successively.
- the order of the layer construction of the light-sensitive material may be changed and also the combination of the couplers may be changed with each other.
- a trichromatic color photographic light-sensitive material having three silver halide emulsion layers each containing a different coupler and having diiferent spectrally sensitizing regions may be processed in the process of this invention.
- the silver halide emulsions used in this invention may be chemically sensitized by a proper combination of sulfur sensitization, reduction sensitization, and gold sensitization.
- gelatin is usually used as a binder for the silver halide emulsion, but it may contain polyvinyl alcohol, polyvinyl acetate, albumin, or a cellulose derivative highly hydrolyzed.
- a hardening agent, an antifoggant, a stabilizer, a surface active agent for coating, and a developing accelerator 7 usually employed may be added to the silver halide emulsion.

- the stability of the colored image of the reproduced drawing and the physical properties thereof were improved.
- EXAMPLE 5 A single layer color photographic light-sensitive material for line image prepared by applying a fine-grain silver chlorobromide positive emulsion containing a cyan coupler to a cellulose triacetate film was exposed and subjected to the following processings to provide a cyan colored reproduction by a process of 33 seconds, in which all processings were conducted at 40 C.
- EXAMPLE 6 As another embodiment of the example shown in Example 5, the following five steps were applied and a sharp image was obtained. All of the steps were conducted at 40 C.
- Stopping solution G. Sodium bisulfite 15 Sodium sulfite 40 Sodium dihydrogenphosphate-2H 25 Sodium acetate 30 Water to make 1 liter.
- Stabilizing solution G. Sodium dihydrogenphosphate-2H 0 30 Sodium thiosulfate 35 Sodium sulfite 30 Water to make 1 liter.
- Example 6 the bleach-stabilizing step was conducted for 20 seconds and the final processing was conducted for 10 seconds in the stabilization bath as in Example 4.
- a process for rapidly developing an exposed color reversal photographic material which consists essentially of a) black-and-white developing the color reversal photographic material for shorter than 30 seconds, said material comprising a support having coated thereon at least one silver halide emulsion layer containing a color coupler, said support being (1) a paper having a weight of less than 100 g./m. (2) a hydrophobic synthetic resin-coated paper, (3) a hydrophobic resinimpregnated paper having a low water-absorbing property or (4) a hydrophobic resin film,
