Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic light-sensitive material for a laser light source, which is excellent in long-term storage stability and processing stability, and is free from residual color contamination and uneven development, and a processing method thereof.

[0002]

2. Description of the Related Art In recent years, images for radiation diagnosis such as MRI (magnetic resonance imaging), X-ray CT (computed tomography), CR (computed radiography), and computer-aided diagnosis systems have been digitally or analogously converted. 2. Description of the Related Art Means have been generalized in which a signal is taken into a processing device such as a computer, scanned with a laser beam, drawn on a silver halide photographic material, and provided as a transmission image for diagnosis.

[0003] Scanning laser exposure apparatuses are used for image recording in these diagnostic apparatuses, and argon, helium-neon, semiconductors, and the like are used as laser light sources. Among them, semiconductor lasers are advantageous in that they are inexpensive, have a long service life, are small in size, and can be directly modulated. In particular, the emission wavelength of a semiconductor laser is in the red to infrared region, and a laser having an emission wavelength of near-infrared is particularly important in terms of cost and stability. However, since the life of the semiconductor laser is said to be inversely proportional to the fourth power of its output, a highly sensitive recording material has been desired in order to extend the life of the device as much as possible.

A method for spectrally sensitizing silver halide grains to the near infrared region is, for example, The Theory of
It is also described in The Photographic Process, Volume 3, pages 198 to 201 (Macmillan. 1966), and discloses the use of long-chain cyanine dyes.

However, the silver halide photographic light-sensitive material spectrally sensitized in the near infrared region is not excellent in storability over time, and storage conditions must be restricted (eg, refrigerator storage) for long-term storage. Further, there are problems that the processing stability is poor, the sensitometric performance is apt to vary depending on the activity of the processing liquid, and residual color stain is left on the film after processing.

Further, when the silver halide photographic light-sensitive material for a laser light source has an emulsion layer on only one side of the support, uneven development processing tends to be noticeable, and uneven development is preferable from the viewpoint of medical image diagnosis. However, a uniform and high-density image was desired.

Conventionally, as a technique for improving the storability of a silver halide photographic light-sensitive material, many reports have been reported including a stabilizer. Further, as a method for improving the residual color contamination of the film, for example, thinning, reduction of the binder, etc. are known, but it is not sufficient from the viewpoint of photographic performance.

On the other hand, in terms of processing of light-sensitive materials, reduction of hydroquinone, which is expensive and environmental pollutant, or free of it has been studied recently in order to reduce environmental load, and reductones are used as compounds replacing hydroquinone. It is being reviewed.

There is no environmental load and the processing stability is excellent,
There has been a demand for a method for processing a silver halide photographic light-sensitive material for a laser light source, which has no residual color on the processed film.

[0010]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a silver halide photographic light-sensitive material for a laser light source, which is excellent in raw storage stability and processing stability of the light-sensitive material and has no residual color contamination and uneven development.
