Problems solved by technology

[0006] Although these photosensitive materials are superior in contrast or sensitivity and color retention, when using an image adjuster to output a flat point of 60%-90%, there is a disadvantage of uneven exposure.

[0345] Preparation of Emulsion A

[0346] Liquid 1: 1 liter of water

[0347] Gelatin 20g

[0348] Sodium chloride 3.0g

[0349] 1,3-Dimethylethylenethiourea 20mg

[0350] Sodium benzenethiosulfonate 8mg

[0351] Liquid 2: 400ml water

[0352] Silver nitrate 100g

[0353] Liquid 3: Water 400ml

[0354] Sodium chloride 27.1g

[0355] Potassium bromide 21.0g

[0356] Ammonium hexachloroiridate (III) (0.001% aqueous solution) 20ml

[0357] Potassium hexachlororhodium (III) (0.001% aqueous solution) 6ml

[0358] The core particles were formed by adding liquids 1, 2 and 3 maintaining pH 4.5 within 15 minutes while stirring at 40°C. Liquids 4 and 5 described below were then added over 15 minutes. Then 0.15 g of potassium iodide was added to complete particle formation.

[0359] Liquid 4: 400ml water

[0360] Silver nitrate 100g

[0361] Liquid 5: water 400ml

[0362] Sodium chloride 27.1g

Embodiment 2

[0492] The following developer solution B was used instead of the developer solution A, and the same exposure and development as in Example 1 were performed on the painted samples 1-12, and evaluation was performed.

[0493] Developer B

[0494] Diethylenetriamine·pentaacetic acid 2g

[0495] Potassium carbonate 33g

[0496] Sodium carbonate 28g

[0497] Sodium bicarbonate 25g

[0498] Sodium Erythorbate 45g

[0499] N-methyl-p-aminophenol 7.5g

[0500] KBr 2g

[0501] 5-Methylbenzotriazole 0.004g

[0502] Sodium sulfite 2g

[0503] Add water to 189 to bring the pH to 9.7.

[0504] result

[0505] From the results shown in Table 2, it can be seen that the sample having the hydrophilic colloid layer containing the non-photosensitive silver halide particles of the present invention had less uneven exposure.

Embodiment 3

[0508] Samples with the same formulation as the coated samples 1-12 were applied with a manufacturing machine at a width of 1 m and a length of 4000 m to prepare samples 1'-12'. It was wound up on a core with a diameter of 20 cm after coating, and stored at 33° C. for 4 days in a wound state. Then, it was returned to normal temperature and normal temperature, processed into a product form, and developed and evaluated in the same manner as in Example 1.

[0509] result

[0510] From the results shown in Table 3, it can be seen that the samples having the hydrophilic colloid containing the non-photosensitive silver halide particles of the present invention had less exposure unevenness.

Abstract

The silver halide photographic sensitive material has a photosensitive silver halide emulsion layer containing at least two silver halide emulsions having mutually different sensitivities and a non-photosensitive hydrophilic colloidal layer containing at least one non-photosensitive silver halide emulsion on the base and contains a hydrazine-base nucleus forming agent and a nucleus formation promoter such as an onium salt in the silver halide emulsion layer or the hydrophilic colloidal layer. The sensitive material is developed at 35 deg.C while replenishing <=200 ml developing solution. Using this silver halide photographic sensitive material it is less liable to cause unevenness in exposure with an image setter and a processing method for the sensitive material.

Description

technical field [0001] The invention relates to a silver halide photographic photosensitive material, in particular to a super-contrast silver halide photographic photosensitive material used for photographic plate making. Background technique [0002] In graphic arts, in order to reproduce a continuous contrast image of a dot image or a line image well, an image forming system having super-contrast (in particular, γ is 10 or more) and photosensitive is required. [0003] An image forming system that uses a treatment liquid with good storage stability for development and can obtain super-contrast photosensitive characteristics as required, as one of them, such as in US Patent No. 4,166,742, No. 4,168,988, No. 4,221,857, and No. 4,224,401 , No. 4,243,739, No. 4,272,606, and No. 4,311,781, treating with a developer solution containing sulfurous acid antioxidant at a pH of 11.0-12.3 and adding a specific hydrazide compound It is a silver photographic photosensitive material an...
