Definitions
- the present invention relates to a method for processing a halogen silver silver color paper (hereinafter sometimes simply referred to as color paper), and in particular, the finished quality of a print obtained by processing the color paper and the processing suitability of a photographic processing solution.
- the present invention relates to a space-saving processing method that can be processed for a short time while maintaining the above.
- mini-lab an automatic development processing device

- the separate bleaching and fixing process which is performed by separating the bleaching solution processing and the fixing solution processing, is applied to photographic light-sensitive materials such as color negative film, and silver chlorobromide type color paper before 1986. Although it was also used in 1986, it was commercialized after 1986 The color paper replaces the silver salt color paper that can be bleach-fixed.
- the photosensitive material that has undergone the color development process moves to the bleach-fixing process while occluded the color developing solution, and thus causes frequent failures such as bleaching fogging and poor color development (leuco dye failure). ing. It has also been found that the occurrence of these failures is suppressed when a separate type bleaching and fixing process is performed.
- a further advantage of the present invention is that the light-sensitive material between the bleaching process and the processing of the solution having a fixing ability avoids air contact, which includes a bleaching tank and a fixing tank having a fixing ability.
- a photosensitive material transport path in liquid is used, which is sealed with liquid nudity so that the photosensitive material can pass between them.

- the photosensitive material passage of this device has an air contact part and is not liquid, so even if this device is used, it is a different process from the submerged transport method. The effect of the in-liquid transport method cannot be expected.
- the total immersion treatment process can also be shortened, so the customer waiting for the minilab is shortened the waiting time for the finish.
- Inkjet method, thermal dye transfer method, thermal development color diffusion The advantage of a short processing time such as a transfer method is relatively reduced.
- a further advantage of the present invention is that the combined processing of the separate processing of the bleaching processing and the processing of the liquid having fixing ability and the in-liquid transport processing of the photosensitive material in which both the tanks are made of liquid is the bleaching processing and fixing ability. Therefore, it is possible to reduce the amount of both the replenishers with a replenishment amount of 35 mL or even 25 mL per lm 2 of the light-sensitive material. This reduction effect is because the bleaching solution can have a higher silver potential than the bleach-fixing solution and the bleaching activity is high, so that the consumption of the bleaching agent can be reduced by that amount, and the contamination of the bleaching solution to the solution having the fixing ability.
- the small amount of replenisher means that the amount of waste liquid discharged due to overflow can be reduced, and the concentrated waste liquid in color paper processing is only the bleach / fixing system waste liquid.
- the waste liquid is returned to the processing agent supplier in accordance with the return of the processing agent container.
- rinse overflow is also discharged. Because it is an aqueous solution with a much lower concentration, it can be used depending on the local regulatory situation.

- UV-2) UV absorber ( ⁇ -3) UV absorber
- the sample prepared as described above was designated as Sample 001.
- Sample 001 was processed into a 127 mm wide roll, and a standard photographic image was exposed using Digital Mira-Lab Frontier 340 (Fuji Photo Film Co., Ltd.). Then the following In this processing step, continuous processing (running test) was performed until the color developer replenisher volume doubled the color developer tank volume. However, Frontier 340 (manufactured by Fuji Photo Film Co., Ltd.) was modified so that the processing speed of the processor would be the following processing time and the tank structure was as shown in Fig. 1.
- composition of each treatment liquid is as follows.
- Optical brightener (FL— 1) 4. Og 9.0 g
- Residual color reducing agent (SR-1) 3. Og 8.0 g
- frontier 340 manufactured by Fuji Photo Film Co., Ltd.
- continuous treatment was performed in the same manner.
- Frontier 340 manufactured by Fuji Photo Film Co., Ltd.
- composition of each treatment liquid is as follows.
- Residual silver amount The amount of residual silver in the black part after processing is measured by fluorescent X-ray analysis.
- Stin Measures the blue light reflection density (status A reflection density for blue light) on a white background.
- Residual amount of the main agent The amount of the developing agent remaining in the color is analyzed by the color development method after extracting the developing agent.
- Processing stability Visual determination of the presence or absence of precipitates in the bleaching running liquid (the presence or absence of residue when the processing liquid is filtered through a microfilter with a pore size of 10 // m).
- Experiment No. 2 which is a comparative example, shows that the amount of residual silver in the black portion of the color paper after processing is lower in the above rapid processing than in the bleach-fixing step, but the minimum minimum density is high. Precipitates are generated. Also, the residual developer concentration is high, which increases the yellow concentration over time at 80 ° CZ70%! ] Is also big.
