Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention is, firstly, a color developing treatment agent for silver halide color photographic light-sensitive materials, a color developing treatment solution for silver halide color photographic light-sensitive materials, and a silver halide color photographic light-sensitive material using these. It relates to a method of processing a material. Secondly, with regard to a method for processing a silver halide color photographic light-sensitive material, in particular, a silver halide capable of performing a dry-like rapid processing, having excellent processing stability, and having a small problem of color turbidity of an image to be formed. The present invention relates to a method for processing a color photographic light-sensitive material.

[0002]

2. Description of the Related Art In recent years, the demand for speeding up processing of silver halide color photographic light-sensitive materials (hereinafter also referred to as "light-sensitive materials") has never stopped, and silver halide grains excellent in developability and fixability have been developed. Various technologies such as couplers with excellent reaction rate and active processing solutions have been proposed and studied. Among these, increasing the concentration of the color developing agent in the color developing solution is one means of activating the processing solution. However, in the practical composition of the color developing solution, there is a limit in increasing the developing speed by increasing the concentration of the color developing agent due to the solubility.

On the other hand, in order to comply with recent regulations regarding waste liquid,
In the so-called minilab, low replenishment is in progress. For this reason, the renewal rate of the processing solution tends to decrease in a minilab where the processing amount per day is small. Especially, a color developing solution having a high concentration for rapid processing is apt to undergo air oxidation, resulting in precipitation of precipitation or tar. And the deterioration of the liquid makes it difficult to maintain stable processing performance. On the other hand, Japanese Patent Application Laid-Open No. 6-324455 discloses a processing method in which a color developing solution is enclosed in a container having a good sealing property and sprayed in order to prevent air oxidation. In that case, sufficient developing characteristics cannot be obtained, and it cannot be put to practical use.

[0004]

By the way, in recent years, the number of minilab stores has increased rapidly, no waste liquid is generated, and even a person who is not accustomed to handling equipment has a dry feeling that does not make you feel that you are using the processing liquid. There is a need for a processing system that can be easily used. In addition, outdoors such as temperature changes,
There is also a demand for a system that can be stably processed in any environment.

In order to obtain processing stability, attempts have been made to keep the composition of the developer constant by directly supplying the developer to the image forming surface (also referred to as emulsion surface) of the light-sensitive material. The direct supply method supplies a relatively large amount of developing solution to the emulsion surface, and not all of the supplied developing solution permeates into the photosensitive material, resulting in liquid sag, which causes the photosensitive material to be conveyed. It was found that the excess processing solution overflows around the path and crystals are deposited, which adversely affects the photosensitive material to be processed next. Therefore, it is necessary that the supply amount of the processing liquid is so small that the liquid does not drip in order to achieve a stable process and a dry feeling.

However, at the concentration of the color developing agent in the color developing solution which is normally used at present, the amount of the main developing agent required to terminate the developing reaction is considerably insufficient with a small amount of the solution supply as described above, and it cannot be used as it is. . In order to supply the amount of color developing agent required for the development reaction to the light-sensitive material with a small amount of solution supply, the concentration of the main agent must be high, but the solubility of the main agent in the color developing solution is low, and crystal precipitation does not occur. Due to problems, it is impossible to increase the concentration in the current color developing solution system.

In JP-A-2-203338, a color developing solution is divided into a low pH solution containing a color developing agent and a high pH solution containing an alkaline agent. It is described that the treatment of color paper is speeded up by improving the permeability of the color developing agent by immersing in a liquid or applying the liquid with a roller. However, when a liquid containing a high-concentration color developing agent is applied to the photosensitive material by such a method, an excessive amount of the color developing agent is present in the photosensitive material, causing a problem of color turbidity.

The inventors of the present invention separated the color developing agent and the alkaline agent into separate solutions, and prepared a solution containing the color developing agent by adding p.
If H is set to a low level, the main component can be contained at a high concentration, and not only can the kit for the color developing solution be made compact, but also if both solutions are made to have a high concentration and individually supplied to the image forming surface of the photosensitive material. It was found that the color development process can be speeded up.

However, in this form, the storability of the liquid containing the main drug cannot be obtained, and when used after storage, a new problem occurs in that the image obtained by processing deviates from the set performance.

The present invention has been made in view of the above circumstances, and firstly, even if a color developing agent is contained at a high concentration by separating the color developing agent and the alkaline agent into separate solutions. It is an object of the present invention to provide a color developing treatment agent for a silver halide color photographic light-sensitive material, which is advantageous in terms of storage stability and, therefore, in kitization and rapid processing, a color developing treatment solution using the same, and a processing method using these. Secondly, there is provided a method for processing a silver halide color photographic light-sensitive material, which enables rapid and excellent stability of processing even when a small amount of developing solution is supplied and does not cause a problem of color turbidity of an image formed. To provide. Thirdly, to provide a processing method of a silver halide color photographic light-sensitive material, which enables stable and rapid processing regardless of the processing amount even if the processing amount is small.

As the processing liquid flying means for flying the processing liquid to the light-sensitive material through the space, a processing liquid having a structure similar to that of the inkjet head portion of an inkjet printer, a structure described in JP-A-6-324455, or the like is used. A liquid is applied to the photosensitive material through a space to generate a pressure in the post-processing flying means to actively fly, or a liquid such as a spray bar that is applied to the post-processing flying means through the space to the photosensitive material. The thing which makes it fly by pressure is mentioned. As a processing liquid flying means for flying a processing liquid having a structure similar to that of the inkjet head portion of an inkjet printer to a photosensitive material through a space, a processing liquid is supplied by vibration or a processing liquid is supplied by bumping. And the like, and it is preferable because the processing liquid supply amount can be controlled and the processing position of the photosensitive material can be selected.

The amount of the partial liquid supplied through the space may be increased or decreased depending on the supply position. Further, at least one of the partial liquids containing the color developing agent or the alkaline agent is supplied through the space, but preferably both are supplied through the space.

Further, as the processing liquid supplying means, even if the processing liquid is supplied from the linear supplying head to the photosensitive material through the space, the processing liquid is supplied from the planar supplying head to the photosensitive material through the space. Alternatively, the processing liquid may be supplied from the dot-shaped supply head to the photosensitive material through a space, or any other method may be used. If the photosensitive material is a sheet, a planar supply head corresponding to the size of the photosensitive material is used to expose the processing liquid from the supply head while the positional relationship between the photosensitive material and the supply head is fixed. The material may be supplied through a space, but it is preferable to supply the processing liquid from the supply head to the photosensitive material through the space while shifting the positional relationship between the supply head and the photosensitive material, even if the supply head is small. It is preferable because the processing solution can be sufficiently supplied to the light-sensitive material. When a linear supply head is used, the supply head may move, but in order to rapidly supply the processing liquid to the photosensitive material, a linear supply head is used instead of the linear supply head. It is preferable to move the photosensitive material in a direction other than the parallel direction. In particular, in order to keep the processing time constant, it is preferable to move the photosensitive material in the direction perpendicular to the linear supply head.

Radiation heating means for heating by radiation of electromagnetic waves and the like.

Further, it is preferable to have a heating control means for controlling the heating means to heat when the silver halide photographic light-sensitive material is present before the heating means heats it, because unnecessary heating can be prevented. This is because the silver halide photographic light-sensitive material is conveyed at a predetermined conveyance speed, and the silver halide photographic light-sensitive material is present at a predetermined position upstream of the heating means by the heating means in the conveyance direction. Can be achieved by controlling the heating control means based on the detection of the photosensitive material. In this case, the control means detects the presence or absence of the silver halide photographic light-sensitive material at the predetermined position after the lapse of a predetermined time after the detection means detects the presence of the silver halide photographic light-sensitive material It is preferable to control the heating means to perform predetermined heating until a predetermined time elapses after the presence is detected and the absence is detected.

It can be seen that the concentration can be obtained. Further, since at least one partial liquid is supplied through the space, it is excellent in process stability and storage stability of the active ingredient, and crystal precipitation and color turbidity can be suppressed. It can also be seen that it is improved and crystal precipitation is further suppressed.

As is clear from Table 6, when the color development processing time is 5 to 45 seconds, the required density can be obtained, color turbidity can be suppressed to a low level, and the effects of the present invention can be fully exhibited.

Example 7 In the processing method 2, the processing liquid supply amount of the partial liquid B was changed as shown in Table 7, and the processing of Example No. 1 of Example 1 was repeated. The treatment was carried out under the same conditions as when starting the continuous treatment in No. 2, and the maximum blue reflection density D _max (Y) of the obtained sample was measured. In addition, the dripping state of the developing treatment liquid was evaluated in the same manner as in Example 3.
