Smith Attorney, Agent, or Firm-Waters, Roditi, Schwartz & Nissen  ABSTRACT Antistatic agents for use in light-sensitive silver halide photographic material comprise bis-aminimide compounds having the formula:
wherein R,, R R and R are individually a lower alkyl group; R and R are individually an alkyl, arakyl or aryl group or a hetero ring; and R is a divalent group.
5 Claims, N0 Drawings PHOTOGRAPH-TIC MATERIAL COMPRISING BIS-ACYLHYDRAZINIUM COMPQUNDS This invention relates to new bis-aminimide compounds. More particularly, this invention relates to a light-sensitive silver halide photographic material which comprises a bis-aminimide compound of the general formula shown later.
A principal object of the present invention is to provide a light-sensitive silver halide photographic mate- 6 e i RzCONIII-Rr- NCO-Ru cite thelight-sensitive material; l r obl fiskfer ivedfrom such static charge are not limited merely to the fonnation of static marks but bring about the adhesion of dust onto the surface of the light-sensitive material. Such static troubles are necessarilybrought about at substantially all stages where light-sensitive materials undergo friction, e.g,, at stages where photographic 7 emulsions are coated on supports, and the resulting sheet films are cut and packed in boxes, or the sheet films are taken out of the boxes and subjected to photographing, and particularly cinefilms which subjected to photographing or handled before. development. The static troubles are brought about also at the time when light-sensitive materials are released. That is, a lightsensitive material, which has been coated with a photographic emulsion and dried, is rolled up, in general, and when this rolled film is successively released in order to subject the film to the subsequent step or to printing, a static charge is generated between the surface and the back of the film at the moment when the film is released from the roll. Further, when a light-sensitive photographic printing paper is subjected to ferrotype drying, a static charge is generated between the surface of the paper and the metal surface at the time when the film is taken up, to cause the phenomenon that the paper cannot be superposed immediately on another one.
For the prevention of such static problems, a moisture-absorptive material is frequently incorporated into a layer of the light-sensitive material. This procedure. however, is effective only when the humidity is relatively high and is ineffective dry periods when static problems are brought about frequently. Further, when the humidity is excessively high, the light-sensitive material incorporated with the moisture-absorptive material becomes sticky on the film surface. In addition to such moisture-absorptive material, a considerable number of compounds have been known as antistatic agents. For application to light-sensitive photographic materials, however, they are required to satisfy such conditions as not to have any detrimental effect on the photographic properties of the light-sensitive material such as sensitivity, gradation, fog, storability, etc. Ac-
cordingly, it is extremely difficult to find excellent antistatic agents applicable to light-sensitive silver halide photographic materials.
wherein RQRQIR and R are individually a lower alkyl group; R and R are individually an alkyl, aralkyl or aryl group or a hetero ring; and R is a divalent group. "fwhfiih'iof the above-mentioned compounds is incorporated into at least one of the silver halide emulsion layer, sub layer, inter layer, filter layer, antihalation layer, protective layer and backing layer, which are constitutive elements of a light-sensitive silver halide photographic material, it is possible to obtain a light-sensitive silver halide photographic material which is extremely less subject to static problems. The incorporation of said compound not only does not have any detrimental effect on the sensitivity, gradation, fog and the like properties of the light-sensitive material .but also displays, depending on the kind of light sensitive material, such favorable effects as to inhibit the fog and enhance the storability of the light-sensitive material. Further, when the compound is applied to a lightsensitive radiographic material, there'is attained the effeet, in addition to the prevention of antistatic troubles, that the color tone of the developed silver image can be made bluish black, and when the compound is applied to an internal color photographic emulsion, the dispersibility of the coupler is enhanced to make it possible to obtain a light-sensitive color photographic material having excellent in resolution and graininess.
