Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a silver halide photographic light-sensitive material containing a novel surfactant, and more specifically, it relates to a silver halide photographic material containing a novel surfactant, and more particularly, it relates to a silver halide photographic material containing a novel surfactant. A halogen compound that does not cause repelling or unevenness, has excellent film properties, can be applied uniformly, is a good dispersant for additives, and contains a specific surfactant that does not adversely affect photographic properties. Related to silver photographic materials.

[Background of the Invention] Generally, a photographic light-sensitive material has a plurality of photographic constituent layers containing hydrophilic colloids provided on a support. These photographic constituent layers have various functions such as an undercoat layer, an intermediate layer, a photosensitive layer, and a surface protective layer. Therefore, when producing photographic materials, gelatin etc. are often used on the support. A plurality of different photographic constituent layers containing hydrophilic colloids may be coated simultaneously, and in this case, the coating solution is coated uniformly and at high speed in a thin layer without causing coating failures such as repelling. required to be applied. In order to satisfy this requirement,
Surfactants have conventionally been added to coating solutions, such as those disclosed in Japanese Patent Publications Nos. 45-5331 and 59-5.
The description thereof can be found in the following publications: No. 0969, Japanese Unexamined Patent Publication No. 51-3219, Belgian Patent No. 708347, Belgian Patent No. 723690, and the like. The surfactant is not only used as a coating aid for cars, but also as an organic solvent for hydrophobic photographic additives such as couplers, ultraviolet absorbers, and optical brighteners, or for hydrophobic synthetic polymers such as acrylic esters ( It is also used as a dispersant when applying a hydrophilic colloid liquid containing a dispersion of polymer latex (hereinafter referred to as polymer latex).

However, surfactants used in photographic materials require photographic properties such as photographic sensitivity, fog, and gradation, and rapid processing properties such as speed of development (i.e., good wetting on the film surface). However, many conventionally used surfactants do not have a negative effect on the hydrophilic colloid liquid, etc. in the presence of a high concentration of electrolyte. It was not preferred as a coating aid in terms of wettability, and as a dispersant for photographic additives, it had a high viscosity and generated a lot of bubbles and cissing. In particular, when polymer latex is added to a hydrophilic colloid layer to improve the physical properties of the film, for example, U.S. Pat.
9051 and JP-A-57-200031, etc., the scratch strength of the hydrophilic colloid layer,
It is necessary to consider dimensional stability, flexibility, etc. In this case, polymer latex tends to aggregate in gelatin, and there is always a concern that it will affect dispersion stability and eventually spreadability, so it is necessary to consider dimensional stability, flexibility, etc. It wasn't. Therefore, when a surfactant is added to a photographic coating solution, uniform application of the photographic coating solution cannot be obtained, and development unevenness occurs during development, and there has been a desire to improve this problem.

[Objective of the Invention] Therefore, the object of the present invention is to have excellent coating properties of a hydrophilic colloid on a support, and furthermore, even if the colloid contains hydrophobic photographic additives or polymer latex, it can be uniformly coated without agglomeration. - It is an object of the present invention to provide an excellent silver halide photographic material which can be dispersed in a silver halide to improve the physical properties of the film and which does not affect photographic properties such as sensitivity and fog.

[Examples] The present invention will be described below based on the following examples, but the present invention is not limited to the following examples.

Incidentally, the % display indicates weight % unless otherwise specified.

Example 1 A high-sensitivity high-contrast emulsion containing 7% gelatin and 6% silver iodobromide (silver iodide 1.5 mol%) was prepared, and 0.01 g of sodium dodecylbenzenesulfonate according to the present invention was added to this photographic emulsion. Exemplary compound (3) was added at 0.00% per 1 kg of emulsion. O1-2.
5g of polyethyl acrylate latex was added as a 2% aqueous solution, and samples with different addition amounts were prepared as shown in Table 1 below.
(solid content: 20% by weight). Each of these emulsions was coated on a cellulose triacetate support having an undercoat layer and dried.

By adding exemplified compound (3) as shown in Table 1,
It can be seen that the number of repellents is greatly reduced.

In addition, even if the exemplified compound contains polymer latex (
It can be seen that as the amount of addition of 3) increases, the number of repellents decreases significantly. Furthermore, even with high-sensitivity, high-contrast emulsions, there was no or very little fogging, and good photographic properties could be obtained.

(Leaving space below) Example 2 Negative photographic emulsion containing 10% gelatin and 8% silver iodobromide (silver iodide 7 mol%) 0.15 g of saponin and polyoxyethylene nonylphenyl ether (daughter of polyoxyethylene) per 1 kg Length: 15) Photographic emulsion containing 0.06 g and 1 kg of 10% gelatin aqueous solution of the exemplified compound (
A dispersion liquid containing 0.10 g of each of 1), (6), and (8) or a known surfactant for comparison was prepared.

Next, the above photographic emulsion and dispersion were simultaneously coated on the undercoated triacetyl cellulose support using a multilayer coating method so that the dry film thicknesses were 5 μm and 1 μm, respectively, cooled and set, and then dried to form samples Nos. 25 was created. The surface protective layer of the obtained sample was inspected, and the number of repellency points of each coating solution was counted. Further, a commercially available phenidone-hydroquinone developer was dropped onto each sample placed horizontally, and the contact angle was measured using a contact angle measuring device (Goniometer Model G-1 manufactured by Elma). Incidentally, the larger the contact angle value, the more difficult it is for the film to wet when immersed in a developer, causing the adhesion of bubbles and uneven development. Therefore, the smaller the contact angle value, the better the development.

's2 table (blank below) *Sensitivity: The reciprocal of the exposure amount at an optical density of 1.50 fog is calculated, and the relative sensitivity is shown with the blank (sample No. 19) set as 100.

As is clear from the above Table 2, sample No. according to the present invention,
Comparative sample N in which sodium lauryl sulfate and sodium dodecylbenzenesulfonate, which are anionic surfactants, were added to Nos. 20 to 22, which had small contact angles and almost no repellency was observed. At 24.23,
Although the number of repellents decreases, the contact angle of the developer dropped on the film surface is large, and the wetting condition with the developer is poor.
It can be seen that uneven development occurs.

Furthermore, it can be seen that comparative sample No. 25 to which polyoxyethylene nonylphenyl ether (n = 10), which is a nonionic surfactant, was added had a large number of repellents during application.

Furthermore, when each of the above samples was developed with a commercially available developer, as shown in Table 2, both the sensitivity and fog were the same as Sample N of the present invention. 20-2
It can be seen that Sample No. 2 is comparable to Comparative Samples N, No. 23 to No. 25, which are conventional products, and is good.
