[57] ABSTRACT A light-sensitive silver halide photographic material containing as anti-spotting agent, at least one compound represented by the general formula e 1 N/CH mCHC OOM 4 Claims, No Drawings I LIGHT-SENSITIVE SILVER HALIDE PHOTOGRAPHIC MATERIAL CROSS REFERENCE TO RELATED APPLICATION This application is a continuation-in-part application of Ser. No. 39,568 filed May 21, 1970 now abandoned.
The present invention relates to light-sensitive silver halide photographic materials containing a novel antispotting agent for preventing so-called spots (white or black stains) which are formed on the surfaces of lightsensitive silver halide photographic materials after development due to such causes as dusts, heavy metal powders or the like which are present in the air.
It has been known that certain kinds of dusts or fine particles of heavy metals which are present in the air become causes for formation of spots on the surfaces of light-sensitive photographic materials. It is considered that spots are formed when such dust-like materials have migrated into light-sensitive photographic materials during the production thereof. In order to inhibit the formation of spots, which injure the photographic properties of light-sensitive materials, it is an ordinary practice to remove dust like materials present in the atmosphere surrounding the steps for production of lightsensitive photographic materials. However, the removal of dust-like materials in the air is quite difficult and is substantially impossible, in practice, because they are generated during the steps for production of light-sensitive materials or brought into the steps to gether with starting materials for the production thereof. It has therefore been desired to prevent the influence on photographic properties of the dust-like materials which have undesirably been contained in lightsensitive photographic materials. In order to accomplish this, there have been adopted processes in which anti-spotting agents are incorporated into layers constituting light-sensitive photographic materials such as, for example, silver halide emulsion layers, inter layers, sub layers or protective layers. However, the conventional anti-spotting agents are not satisfactory yet, and have the disadvantage of undesirably reacting with other photographic additives present together therewith or with the developers.
A principal object of the present invention is to overcome the above-mentioned drawbacks of the conventional anti-spotting agents and to provide light-sensitive photographic materials having excellent photographic properties.
As the result of extensive studies, we have found that compounds represented by the general formulas l and II are excellent anti-spotting agents and that lightsensitive photographic materials incorporated with said compounds have such excellent characteristics that they are not affected at all by dust or fine powders of such heavy metals as iron, copper, tin, lead, chromium and nickel and oxides thereof which are present in the air, and they are not degraded in inherent photographic properties.

Other compounds employed in the present invention can also be synthesized according to the abovementioned synthesis procedures. The thus obtained compounds of the aforesaid general formulas may be used either singly or in admixture, and are incorporated into silver halide emulsion layers in an amount within the range of 1 X to l X 10" mols per mol of silver halide, or are incorporated into sub layers, inter layers or protective layers in an amount within the range of 5 X 10' to l X 10 mols per square meter, whereby the formation of spots due to dusts, heavy metals or oxides thereof in the air or due to other causes can be effectively prevented. If necessary, the compounds may be added in an amount out of the above-mentioned ranges.
Ordinarily, the extent of spot formation varies de' pending on the pH values of silver halide emulsions, and some of the known anti-spotting agents have a tendency to be varied in anti-spotting action clue to variation in PH of silver halide emulsions. However, the.
aforesaid compounds employed :in the present invention do not substantially vary in effectiveness at a pH range of ordinary silver halide emulsions, regardless of whether they are acidic or alkaline. and hence are markedly effective. Further, the compounds employed in the present invention are not injured. Moreover, the effects of the compounds are not dominated by the kind of supports and of materials of sub layers, and thus the compounds are effectively applied to all the lightsensitive silver halide photographic materials such as usual black-white and color films specific specif lightsensitive printing and X-ray materials.
The present invention is illustrated in further detail below with reference to examples, but it is needless to say that the present invention is not limited to these examples.

Emulsion A was incorporated with 0.5 g. of the compound of exemplification l0 and then coated on a polyester support to prepare a sample A. On the other hand, emulsion B was coated as it was on a polyester support to prepare a sample B. After setting, each sample was sprinkled with a nickel powder, dried, cut and then subjected to development. As a result, a large number of spots were formed in sample B, whereas no formation of spots was observed in sample A.

Emulsion C was coated as it was on a polyester support to prepare a sample C. On the other hand, emulsion D was incorporated with l g. of the compound of exemplification 5 and then coated on a polyester support to prepare a sample D. Each sample was sprinkled with dust collected from the air and then dried, out and subjected to development. As a result, a large number of spots were formed in sample C, whereas no formation of spots was observed in sample D. Further, no degradation in photographic and physical properties was observed in sample D.

Sample E was coated with an aqueous gelatine solution containing 2 g. of the compound of exemplification 14 to form a protective film thereon. On the other hand, sample F was coated with an aqueous gelatine solution. Each sample was sprinkled with dust collected from the air and then dried, out and subjected to development. As a result, no formation of spots and no degradation in photographic and physical properties were seen in sample E, whereas a large number of spots were formed in sawmi l- A sub-coating liquid for a polyester support was divided into two portions G and H. Portion G was incorporated with 3 g. of the compound of exemplification l5 and then coated on a polyester support, followed by drying, to prepare a sample G. On the other hand, portion H was coated as it was on a polyester support, followed by drying, to prepare a sample H. Each sample was coated with a low speed regular type silver iodobromide photographic emulsion and, after setting, the
sample was sprinkled with iron powder, dried, cut and subjected to development. As a result, no formation of spots was observed in sample G, whereas a large number of spots were formed in sample H.

Emulsion l was incorporated with 0.1 g. of the compound of exemplification 8 and coated on a baryta paper to prepare a sample I. On the other hand, emulsion J was coated as it was on a baryta paper to prepare a sample .1. After setting, each sample was sprinkled with chromium powder, dried, cut and subjected to development.
