Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to an internal latent image type direct positive silver halide photographic light-sensitive material (hereinafter referred to as an inner latent type direct positive light-sensitive material) and a negative type silver halide photographic light-sensitive material. The present invention relates to a development processing method in which a material (hereinafter, referred to as a negative type photosensitive material) is processed with a common developing solution.

BACKGROUND OF THE INVENTION The methods used for producing a positive image using an inner latent type direct positive photosensitive material can be mainly classified into two types in consideration of practical usefulness, except for special ones. .

One type uses a previously fogged silver halide emulsion and obtains a positive image after development by destroying fog nuclei (latent image) in the exposed area by utilizing solarization or Herschel effect. .

In another embodiment, a positive image is obtained by using an unfogged internal latent image type silver halide emulsion and performing surface development after image exposure or after fog treatment or while performing fog treatment.

The above-mentioned internal latent image type silver halide emulsion means a silver halide photographic emulsion having a photosensitive nucleus mainly inside the silver halide grain and forming a latent image inside the grain upon exposure.

This latter type method is generally more sensitive than the former type method and is suitable for image formation requiring high sensitivity, and the present invention relates to this latter type. .

Various techniques have been known so far in this technical field. For example, U.S. Patents 2,592,250 and 2,466,957
No., No. 2,497,875, No. 2,588,982, No. 3,761,266,
No. 3,761,276, No. 3,796,577 and British Patent 1,151,36
Those described in No. 3 and the like are the main ones, and by using these methods, a photographic light-sensitive material having relatively high sensitivity as a direct positive type can be produced.

Although it is hard to say that a clear explanation has been given so far regarding the details of the formation mechanism of the direct positive image, for example, the Theory of the Photographic Process by Mies and James was published. the Phot
The process of forming a positive image can be understood to some extent by the "desensitizing action by an internal latent image" as discussed on page 161.

That is, by the surface desensitizing effect resulting from the so-called internal latent image generated inside the silver halide grains by the first image exposure, fog nuclei are selectively generated only on the surface of the unexposed silver halide grains, It is considered that a photographic image is formed on the unexposed area by the development of.

As described above, as a method for selectively generating fog nuclei, a method of fogging with a chemical such as a fog agent called "chemical fog" and a full exposure called "light fog" are given. It is known how to put on.

By the way, in the case of processing the inner latent type direct positive photosensitive material in the photo lab, a processing line dedicated to the inner latent type direct positive photosensitive material is provided separately from the conventional negative type photosensitive material processing line. It is common to have

The processing line for negative-working photosensitive materials comprises, for example, three types of equipment, an automatic developing machine for negative film, an automatic developing machine for negative paper, and an automatic printing apparatus, which are separately arranged. The photosensitive material processing line is composed of two types of equipment, a dedicated automatic printing apparatus and a dedicated automatic developing machine. Generally, a work space of a predetermined size is required around each of these devices, and a space necessary for adjusting the refill cock, evaporation correction, tank liquid exchange, and refill work is secured around these devices. There must be.

Therefore, when the above-mentioned devices are separately arranged, it is necessary to prevent the work spaces from overlapping around the respective devices, which may hinder the work in a small space such as a small-scale color photofinishing laboratory. The simplification of the processing method and the downsizing of the automatic processor have become important issues.

Against this background, the present inventor has continued research on processing an inner latent type direct positive photosensitive material and a negative type photosensitive material with a common developing solution.
An attempt was made to process an inner latent type direct positive photosensitive material and a negative photosensitive material by a chemical fogging method with a developer having the same composition, but the occurrence of fogging of the negative photosensitive material was remarkable. Developers that commonly process internal latent direct positive and negative photosensitive materials require maintenance and control of the activity of the solution more than other processing solutions, and are generally at higher temperatures than other processing solutions. It has been found that it is not easy to suppress the occurrence of fogging on the negative-type photosensitive material because the temperature must be set.

Therefore, the present inventor examined the optical fogging method. That is, when developing an internal latent type direct positive photosensitive material, the light source for giving the entire surface exposure is turned on, while when developing a negative type photosensitive material, both light sources are turned off. An attempt was made to develop the materials in common, but it was found that this optical fogging method also had the following problems.

That is, by adopting the above-mentioned optical fogging method, it has become possible to process an inner latent type direct positive photosensitive material and a negative photosensitive material with a common developing solution. However, for example, the developing solution replenishment suitable for each photosensitive material is performed. However, it was found that the coloring of the liquid occurred and the concentration of the coloring dye changed due to the filter effect of the secondary exposure.

As a result of intensive studies by the present inventors, one of the causes of the coloring of the liquid is an oxidized coloring matter having absorption at a specific wavelength, which causes yellow coloring and causes a decrease in coloring density of the yellow dye and stain. Secondly, it was found that, secondly, the color density of the anti-irradiation dye (called AI dye) used for improving the sharpness of the light-sensitive material was lowered and the stain was generated. These problems have a great influence especially when an inner latent type direct positive sensitive material is used, but a problem of stain occurs also in a negative type sensitive material.
