Abstract

PURPOSE:To obtain a stable color image through stabilization processing without rinsing, by color developing a photographic material, fixing it with a bleach fixing soln. contg. polycarboxylic acid iron salt, and processing a 3-8pH buffer soln. cong. at least one of phosphoric acid and boric acid. CONSTITUTION:A dye-forming type silver halide color photosensitive material having color couplers is color developed, and bleach-fixed with a bleach-fixing soln. containing the iron salt of polycarboxyl acid. A color image is stabilized by processing with 3-8pH aq. buffer soln. containing at least one of phosphoric acid and boric acid, without rinsing it. Use of this process permits an amount of water used per m<2> of photosensitive material to be reduced to about 1/10 of conventional process. Thie stabilization soln. is prepared by dissolving 4.5g dihydrogen potassium phosphate in 1 liter water to give 5.0pH value. Use of this stabilization soln. for 1min stably forms a fog-free color image having good image density.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing method for color photographic photosensitive Hamura, and more particularly to a stabilizing process for washing the color photographic photosensitive Hamura.

Generally, when processing a color photographic photosensitive Hamura, a color image is obtained by desilvering after color development, but washing with water is always required before and after each processing step. On the other hand, there is a demand for a processing method that does not require a water washing process, and for black and white photographic paper, stabilization processing (that is, a process that completely stabilizes the image without a water washing process; 'l', l(, Jam
es"The Theory of tbePh
otograpbic Process Ived
(See P4'+4c) There are patent applications filed after 3 years ago.

(British Patent No. Sr, RTO; US Patent No. 1゜4tj
No. 3.34; same No.-, 1163, J-Hiro No. 7; same No. 2
, 4<+tJ', No. 57, etc.) Furthermore, around 1960, the black and white developer began to process (stabilize) the black and white developer using a stabilizing solution such as alkaline treatment and rotanite. Therefore, development processing (such as stabilization processing of Hatashi Riikku's swear words) that does not require washing with water is widely practiced.

As a result, a patent (West German Patent No. 1,
772. ≠ No. J) was also submitted to fc.

However, the method according to this patent was not widely available on the market due to poor stability of the color image that produced eyebrows on a white background.

The above-mentioned stabilization processing liquid for black and white bad phase actually only performs image stabilization processing, but silver original white and fixing processing are not performed at all, or in the stabilization processing for color Wu, light etc. In addition to so-called stabilization, it is also necessary to simultaneously or continuously perform silver whitening and fixing.

Therefore, it cannot be applied to the stabilization process H'e color printing that is performed on black and white photographic paper, and it is thought that it is difficult to put this stabilization process into practical use in color silent theater VC. Ta.

By the way, in the processing of color sensitive materials, there is a similar name to the stabilization treatment or stabilization treatment liquid referred to here, which is called stabilization bath (1 stabilizer). This stabilizing bath is used for processing after the final water wash as a method of increasing the stability of the color image after processing.
This is a type of eye bath made of a hardening agent, which is completely different from what we call a stable treatment immediately after the firewood white foot treatment (no water rinsing treatment).

Furthermore, in recent years, in urban areas, the cost of supplying washing water for photographic processing has become increasingly expensive, and the discharging of washing wastewater also costs a huge amount of money, so there is a strong desire to conserve water.

Moreover, due to the dependence of oil, there was also the problem that heating the washing water required a great deal of expense.

Therefore, there is a need for a processing method that increases the stability of color images after processing by stabilizing color photosensitive materials, and also eliminates the need for the washing process that consumes a large amount of water and noise, which was previously performed. Ta.

Accordingly, a first object of the present invention is to provide a color stabilization processing system that does not necessarily require a water washing step when performing color photoresist color phenomenon, bleach-fixing processing.

The second object of the present invention is to improve the stability of color images after processing in color development and bleach-fixing processing methods for color sensitive materials, compared to the conventional processing power method using water washing processing. The object of the present invention is to provide a method for stabilizing color photosensitive materials.

These objects of the present invention are to perform color development using a silver halide color photosensitive dye color developer containing coupler gold, bleach-fixing with a bleach-fixing solution containing an iron salt of polycarboxylic acid, and then rinsing without washing with water. Acid fc is treated with a water bath solution containing at least 7 types of boric acid and has a buffering capacity of pH J~r, and the color image is completely stabilized by a completely new processing method. Achieved In other words, we challenged the conventional wisdom that stabilizing color photosensitive materials is difficult, and found that the above method is an extremely excellent stabilizing method.

The processing method of the present invention increases the stability of color images and eliminates problems such as fogging over time. Furthermore, in the conventional processing method, washing with water consumes at least IOt of water sound and takes 3 to 10 grams of water (at least 2 minutes) to wash the sensitive material. Washing with water is not necessary, and the feeling is U'/m.
It is now possible to perform the process using at most 2 to 9 parts of water and a processing time of about 1 minute.

Furthermore, if necessary, gold may be added to hardeners (formalin, etc.), fluorescent brighteners, surfactants, etc. 〇Furthermore, treatment with a stabilizing treatment solution and washing with water, for example, rinsing with water, as necessary. You may also perform spray washing, etc.
