Definitions

  • a photographic element comprising a support having thereon at least one light-sensitive silver halide emulsion layer and at least one gelatin layer containing R. R;-+l ⁇ I-CH( JH ,.Coo
  • R R and R which may be the same or different, each represents an aliphatic hydrocarbon radical, R and R which may be the same or different, each represents a hydrogen atom or an aliphatic hydrocarbon radical, and the total of the carbon atoms in R to R is from 8 to 21, and n is 0 or 1.
  • This invention relates to a silver halide photographic light-sensitive element containing as its constituent photographic coatings composed mainly of a mordant, a dye and a betaine type surfactant which is employed as coating aids.
  • the purposes of the present invention are to improve the wetting property of a photographic coating composition; to provide uniformity to a film after the application of the coating composition; and to present a silver halide photographic light-sensitive element in which the diffusion of the dye from the photographic coatings thus obtained to its adjacent photographic emulsion layer is prevented in the formation of the photographic coatings containing the dye which serves as light filtering layer such as yellow filter layer and light absorbing layer such as antihalation layer.
  • a photographic light-sensitive element is generally constituted of a support, such as one of cellulose triacetate, polycarbonates, polyesters, other synthetic polymers, glass or paper; a subbing layer, an antihalation layer, a photographic emulsion layer, an intermediate layer, a filter layer and a protecting layer etc., which are provided in order on the support.
  • the photographic light-sensitive element is generally composed of a number of layers. These layers can not be applied uniformly where the coating composition is not employed along with a surfactant which serves to spread the coating composition uniformly and to improve its wetting characteristics. The surfactant also ice has the effect of suppressing the formation of foams and the repellency of the coating composition.
  • a coating composition containing a photographic emulsion having a different composition or a polymer material, such as gelatin may be continuously coated in some cases in a multilayered manner on a support in the production of a color photographic light-sensitive element.
  • a coating composition or a photographic emulsion containing gelatin on a gelatin layer more difiiculties are encountered in obtaining the required wetting characteristic in comparison with that encountered in the direct application of a gelatin coating composition to the support.
  • Saponin has been widely employed as coating aids for many years in the photographic industry and more widely utilized than a number of other surfactants.
  • saponin has such disadvantages that it is liable to foam and there is large variation in its quality between batches due to the fact that it is natural product.
  • synthetic surfactants turn out to be employed in the photographic industry in recent years and a number of patents concerning this have been already published.
  • the synthetic surfactants disclosed in these patents are not only employed as coating aids but also have the effects of static charge prevention, an increase in the solubility of color couplers, the permeability of a treating composition, a decrease in difiiculties due to a waterdrop, a disappearance of bubbles on the application of a gelatin sol to an emulsion layer which is set on cooling, development acceleration, and on prevention of stain due to the antihalation dye on a support.
  • An example of the difficulties encountered in the coating process in the production of photographic light-sensitive element is to coat uniformly a mordant-dye type colloid dispersion in which the mordant and the dye are dispersed in a considerably diluted gelatin solution. Coating of this colloid dispersion has been usually employed as antihalation layer or filter layer in the photographic light-sensitive element. However, in this case, it was almost impossible to obtain a homogenous mordant-dye type dispersion and to apply it to a coating surface without foam formation or repellency.
  • the diffusion of the dye is attributable to formation of a binding between the mordant and the anionic surfactant, which leads to isolation of the dye, due to the fact that the binding strength of the mordant and the anionic surfactant is stronger than that of the mordant and the dye.
  • non-ionic surfactants such as saponin or polyalkylene-oxide derivatives
  • diffusion of the dye and cohesion of the mordant with the dye can be surpressed whereas wettability with a subbing layer is found to be bad, thereby causing repellency of a coating composition to occur. This phenomenon is especially remarkable under high speed coating operations.
  • Cationic surfactants such as N-alkyl-N,N-dimethyl-N- benzylammonium chloride, have similar antidiifusion effeet on the dye but striking cohesion of the dye and formation of fog, etc., are accompanied therewith, thus causing photogrpahic properties to be worse and hence there is little practical importance.
  • an N-alkylaminopropionic acid type amphoteric surfactant can be employed as coating aids for a coating composition forming a decolorizing filtering layer, comprising benzoxazolepyrazolonemelocyanine dye having a sulfonyl-, a sulfoalkylsulfophenyl-, a carboxylor a carboxylalkyl radical in its aromatic nucleus, and a basic high molecular weight mordant, such as a poly-alpha-methylalkyl-N-guanidylketoimine, to prevent diffusion of the dye and consequently to give a uniform mottleless film.
  • a basic high molecular weight mordant such as a poly-alpha-methylalkyl-N-guanidylketoimine
  • a coating aid such as sodium coco-beta-aminopropionate, described in the above British patent, is employed for a coating composition forming a decolorizating filtering layer, comprising a poly-Z-methyl-l-vinylimidazole type high molecular weight mordant and a dye, described, for example, in the specification of US. Pat. No. 3,445,231.
  • the present invention relates to application of a gelatin solution containing a mordant and a dye, which is diflicult to coat.
  • the primary object of the present invention is to provide a photographic light-sensitive element having improved wetting and anti-repellent characteristics on the application of a gelatin solution comprising a basic high molecular weight mordant and an acidic dye, containing a betaine type surfactant, on a support or on other photographic layers.
  • Another object of the present invention is to apply a photographic composition without formation of any bubbles and other difiiculties on its application.
  • Another object of the present invention is to facilitate application where a photographic gelatin or emulsion layer is coated simultaneously or in order with another or still another gelatin or emulsion layer or layers.
  • Another object of the present invention is to prevent diffusion of the dye, thereby the sensitivity of this adjacent.
  • photographic emulsion layer is prevented from lowering.
  • Still another object of the present invention is to prevent cohesion of the mordant with the dye so as to give a stable coating composition.
  • R R and R which may be the same or different, each represents an aliphatic hydrocarbon radical, R and R which may be the same or different, each represents a hydrogen atom or an aliphatic hydrocarbon radical, and the total of the carbon atoms in R to R is from 8 to 21, and n is 0 to 1, to a gelatin composition containing a high molecular weight mordant having basic radicals, such as a polymer comprising more than 50% of Z-methyl-l-vinyl-imidazole units or the quaternary salts thereof, a polymer comprising more than 50% of 2-(or 4-) vinylpyridine units or the quaternary salts thereof, or a polymer comprising more than 50% of alkylaminoalkylacrylate units or alkylaminoalkylmethacrylate units or the quaternary salts thereof, and an acid dye, i.e., an oxanol or a pyrazolonestyryl type dye containing an acidic radical in its aromatic nu
  • betaine compounds may be converted to its carboxylate in an aqueous alkali solution.
  • betaine type surfactants which are employed in the present invention show peculiar effects in view of the same amphoteric type surfactant as described in the above British patent specification of No. 1,124,490. Accordingly, the betaine type surfactants represented by the above general formula are employed in the present invention to form a uniform film without having any undesirable properties, e.g., diffusion of the dye, cohesion (precipitation) of the mordant with the dye, and repellency etc. There is also no adverse influence on the photographic properties.
  • R to R in the above betaine type surfactant generally will contain an aliphatic chain of from 1 to 18 carbon atoms, for example, alkyl groups such as methyl, ethyl, propyl, isopropyl, butyl, hexyl, octyl, decyl, dodecyl, hexadecyl, octadecyl, oleyl and the like.
  • mordants and dyes are illustrative of those which can be used in the present invention, but it should be understood that these compounds are not a limitation thereof, i.e., preferably employing any of an oxanol or pyrazolone-styryl type dye containing an acidic radical, such as a sulfo or a carboxyl radical, etc., and capable of being decolorized during the course of the treatment, or a basic high molecular weight mordant having a basic group in its main or branched chain, such as a poly-Z-methyl-l-vinylimidazole, a polyalkylaminoalkylacrylate or a polyalkylaminoalkylmethacrylate, or a poly- 2(or 4)-vinyl-pyridine group.

  • This betaine compound may be employed alone as a coating aid, or may be employed together with a nonionic surfactant, such as saponin or a polyalkylene oxide derivative, or an amphoteric surfactant, such as alanine.
  • a nonionic surfactant such as saponin or a polyalkylene oxide derivative

  • the proportion of mordant, dye and colloidal binder may be varied over a wide range and will depend on the specific requirements of the photographic element being produced.
  • the present invention is applicable to a photographic light-sensitive element con taining at least one layer selected from a decolorizing antihalation layer, a filter layer and intermediate layers, composed of the mordant, the dye and the betaine type surfactant.
  • These layers are especially necessary to obtain a color photographic light-sensitive element having high resolving power and sharpness, serving as an effective antihalation layer when the base is not colorized, affecting little irradiation between the layers and capable of being applied to an emulsion layer on a support.
