BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic light-sensitive material for photolithography, and more specifically, it has excellent safelight durability in a working room and has improved dot quality and blank character quality. The present invention relates to a silver halide photographic light-sensitive material in which the residual color of a dye, the transferability of color fading and the like are reduced and there is no coating trouble in the production of a light-sensitive material.

2. Description of the Related Art A pattern in photoengraving is formed by a halftone dot image and expresses the shade of a printed matter according to the halftone dot area.
In the plate making process, a continuous scan original is turned on / off with a laser scanner or a camera that uses a contact screen.
Of the halftone dot image, the step of enlarging / reducing the halftone image using a camera, or the step of photographing a character reflection original and converting it into a character transparent original, the halftone image transparent original obtained in these steps. And the line image transparent original are superposed on each other, and the combined exposure is performed.

The silver halide photographic light-sensitive material used in these steps has no deterioration in quality such as sensitivity, halftone dot, and character line drawing even if it is handled for a long time under a safe light for work in a working room. In addition, it is required that there is no residual color contamination in the rapid development processing.

Conventionally, it has been common in the art to provide a dye layer on the outside of the emulsion layer to substantially block safelight light for the purpose of improving the durability of safelight. It is also well known to provide an antihalation layer containing a dye under the emulsion in order to prevent deterioration of image quality due to so-called halation in which light transmitted to the photosensitive layer is reflected from the support interface, back surface, etc. to expose the photosensitive layer. Has been.

The dyes used in these layers are excellent in decoloring property and solubility in rapid processing, and it is an essential element not to leave residual color stain in the layers. Therefore, dyes having high water solubility are usually used. ing.

Generally, a water-soluble compound having no adsorptive functional group easily moves within the layer during the production of a light-sensitive material. Therefore, the dye diffuses and migrates to the silver halide emulsion layer, resulting in a significant decrease in sensitivity and a marked deterioration in the quality of halftone dots and drawn character line drawing.

Further, when a highly water-soluble dye is used in the backing layer, when the film is handled with bare hands, the dye is transferred to the hands of workers, causing discoloration.

A method of making the dye itself non-diffusible as a means for preventing diffusion transfer of the dye to another layer is described in US Pat.

Although 3-184749 and 63-316852 are disclosed,
None of these dyes has a decolorizing property or a solubility in a processing solution, and thus has a drawback of increasing residual color contamination.

Further, as a method of fixing a dissociative dye to make it non-diffuse by using a mordant, for example, US Pat. No. 2,548,564,
Nos. 3,625,694 and 4,124,386 are disclosed.

However, in this method, a binder such as gelatin in the light-sensitive material constituting layer forms an aggregate with a mordant or increases the viscosity, which causes serious troubles such as uneven coating and cissing. As a separate method, the pK of the dye itself

However, this method requires the dye molecules
As a result, the kind of dye is structurally limited to give pKa, and it is difficult to obtain a dye having a desired absorption wavelength. Therefore, a new technique for non-diffusing a dye having a good decolorizing property and a desired spectral characteristic has been strongly desired.

The irradiation time was changed by the safe light amount of ux, and the time for which the fog density after processing increased by +0.0035 according to the processing conditions shown below was defined as T (minutes).

The pH of this fixer was about 4.6.

Next, using a test sample that was not irradiated with safelight light, using a bright room printer P-627FA manufactured by Dainippon Screen as an exposing machine for returning, a 50% hard dot halftone transparent original having a thickness of 100 μm was used as an original. The number of seconds of exposure that was used for exposure and returned to 50% after processing under the above processing conditions was defined as C (second).

From the above test, the substitute value SL for safelight durability was determined as (LogT + LogC). The larger the SL, the better the safelight durability.

(Evaluation of quality of blank characters) 100 μm thick transparent sticking base in order from the light source side of the bright room printer, 80
Black line image with a line width of μ 100μ thick transparent original, 100μ transparent transparent base, 100μ thick 50% hard dot halftone transparent original made into 4 layers as an original, exposed to the test sample, then the above automatic development Processed. The degree of collapse of the line image at the exposure amount at which the halftone dots return to 50% is measured as the width of the missing D
(Μm). This D is called a blank character width and is an evaluation value of blank character quality. The larger D means the better result.

(Evaluation of Residual Color) As a substitute for natural aging, a test sample was stored in an environment of 40 ° C. and 20% RH for 1 day, and then subjected to the above-mentioned automatic development treatment in an unexposed state to give 5 treated test pieces. The sheets were piled up and the degree of coloring was visually evaluated in five levels. The level of the test piece without addition of the dye was set to 5, and the number of overlapped target test pieces, which is the same as the overlap of the sample without addition of the dye, was used as each rank. However, all the inferior ones were ranked as rank 1.

(Increase in viscosity of coating liquid) Emulsion protective layer coating liquid P1
After adjusting P17 to P17, the mixture was kept warm at 35 ° C and the viscosity at 35 ° C was measured. The higher the viscosity, the more the coating properties are adversely affected.

The results obtained are shown in Table 2 below.

[0076]

[Table 2]

As is clear from Table 2, the samples according to the present invention have a significantly improved safelight durability and the quality of blank characters as compared with the case where the dye is simply added. It was found that good results were obtained without any coating problems due to an increase in the viscosity of the coating liquid during manufacturing.

Example 2 Sample Nos. 18 to 34 were prepared by the same method as in Example 1. However, whereas in Example 1 the non-diffusible silver salt of the dye of the present invention was added to the non-photosensitive hydrophilic layer (specifically, emulsion protective layer) on the photosensitive layer side, in Example 2 the backing layer was used. The non-diffusible silver salt of the dye of the present invention was added to the coating solution.

The backing layer coating solution used was the same as in Example 1 except that the dyes C and D were omitted.

The details of the sample are shown in Table 3 below.

[0081]

[Table 3]

(Evaluation Method) The quality of blank characters, the residual color and the viscosity of the coating solution were evaluated in the same manner as in Example 1, and the discolorability of the dye from the film was evaluated as follows.

(Evaluation of discoloration on hands) Each of the prepared test samples was conditioned at 23 ° C. and 80% RH for 1 day, and then in this environment, the BC surface side of the photosensitive material was strongly rubbed 100 times with absorbent cotton. .. The degree of coloring of the absorbent cotton attached by this operation was visually evaluated in the following 5 grades.

1: Extremely large coloring 3: Slight coloring 5: No coloring The obtained results are shown in Table 4 below.

[0085]

[Table 4]

As is clear from Table 4, the sample of the present invention has a marked improvement in the color loss on the hand and the quality of the removed characters, as compared with the case where the dye is simply added, and the residual color or the color after rapid processing. It was found that good results were obtained without any coating problems due to an increase in the viscosity of the coating liquid during manufacturing.
