Abstract

PURPOSE:To obtain the titled photographic sensitive material having stable quality causing no coating defect such as spot by treating the surface of the base with a water-soluble oxidizing agent before or during coating photosensitive silver halide emulsion on a photographic base. CONSTITUTION:An aimed silver halide photographic sensitive material is obtd. by treating the surface of a base material with a water-soluble oxidizing agent before or during coating a photographic base material such as glass or polyethylene coated paper with a photosensitive silver halide emulsion. Specific examples for the water-soluble oxidizing agent are potassium ferricyanide, potassium bichromate, ferric ammonium salt, cupric chloride, potassium permanganate, etc. The amt. of the water-soluble oxidizing agent to be used is suitably about 5X10<-4>-5X10<-2>mol/m<2>, and it is preferred to apply a soln. contg. the water-soluble oxidizing agent to the base material and to dry the coated base material before the photosensitive silver halide emulsion is coated on the base material.

[Background of the Invention] Water-soluble sulfur-containing substances contained in atmospheric dust are used in the manufacturing process of silver halide photographic materials, particularly during the coating and drying steps. Dot-like or streak-like spora 1 on the image surface obtained by development by adhering to the body surface or the surface of the constituent layers of the photosensitive material.
A failure occurs. Therefore, great care and efforts are being taken to prevent the above-mentioned dust, which has an adverse photographic effect, from being mixed into the manufacturing process of silver halide photosensitive materials. However, while dust in the atmosphere is removed by passing it through extremely fine filters or by passing the air into water, it may adhere to the support that is the material of the photosensitive material and enter the manufacturing process. The reality is that complete removal is nearly impossible due to the presence of people in the process.

Example 4 The sample preparation method was changed as follows in the same manner as in Example 3,
A water-soluble oxidizing agent-containing solution was applied to the lower layer, and a silver halide emulsion solution was applied to the upper layer by a simultaneous multilayer method, and dried to obtain each sample.

結果を表−4に示す。The results are shown in Table 4.

尚、下層の液にはゼラチン396を含有させた。Note that the lower layer liquid contained gelatin 396.
