Definitions

  • This invention relates to anti-halation layers for photographic materials and particularly to such layers containing an alkali soluble resin.
  • the present day photographic materials such as black and white and multilayer color films, have an anti-halation layer interposed between the support and silver halide emulsion layer, as an overcoating over the silver halide emulsion layer when such emulsion is exposed through the support, or as a backing layer, i. e., on the support opposite the silver halide emulsion layer.
  • the general practice in preparing such layers is to disperse or dissolve an anti-halation dye or pigment in a colloidal dispersion of gelatin or in a solution of an alkali soluble resin.
  • the gelatin layer is undesirable not only because of its high coefficient of friction, its low abrasion resistance, and its lack of flexibility, but also because it offsets and blocks readily.
  • alkali soluble resins are currently used to replace gelatin and have many advantages over gelatin, i. e., readily soluble in alcohols and in alkaline developers, they too, like gelatin, offset and block readily.
  • the primary object of the present invention is to provide a new anti-halation layer which will not offset and block.
  • the concentration of the fatty acid amide or mixtures thereof may vary from to 50% of the weight of the alkali soluble resin.
  • alkali soluble resins i. e., those readily soluble in the usual alkaline photographic developing baths, are susceptible to offset and blocking, any one of them may be stabilized against these effects by the addition of the fatty acid amides. Resins of this type'are legion and no difficulty Will be encountered by those practicing this art to select any resin-for a particular film:
  • Alkali soluble resins in which the acid groups are in the form of anhydrides as described in U. S. P. 2,161,788 may be employed.
  • copolymers of maleic acid anhydride and styrene, or vinyl butyl ether, vinylisobutyl ether, or vinylethyl ether may also be employed.
  • anti-halation dyes or pigments which may be incorporated into the dispersion of the alkali soluble resin are well known and need not be illustrated in detail.
  • silver salts of hydroxyazaindolizines such as 6 [5,7 disulfonaphthalene 1 azo] 7 hydroxy 5 methyl 1,3,4 triazaindolizine, 5 [3,5 dicarboxy phenyl 1 azo] 4- hydroxy-6-methyl-2,3,7-triazaindolizine, and the like, disclosed in U. S. P.
  • xanthylium dye salts such as 3,9 dihydroxy 6 p-methoxystyrylxanthylium chloride, 3,9 dihydroxy 6 p diethylaminostyryhtanthylium chloride, 3,9 dihydroxy 6 p dimethylarninostyrylxanthylium chloride, and the like, disclosed in U. S. P.
  • pyrylium dye salts such as 4(4-dimethylaminostyryl) 7 hydroxy Z-phenylbenzopyrylium chloride, 2,4 dihydroxy 2 styryl benzopyrylium chloride, 4-hydroxy-2-styrylbenzopyrylium chloride, and the like, as disclosed in U. S. P. 2,461,484; the triphenylmethane derivatives disclosed in U. S. P. 1,912,797, 2,098,891, 2,147,112, 2,150,695, and 2,282,890; the dyestuff combinations disclosed in U. S. P. 1,923,485; the methine and polymethine dyes disclosed in U. S. P. 2,268,798, 2,298,731, and 2,298,733; Prussian blue, titanium dioxide, manganese dioxide, carbon black, and the like, may be employed.
  • pyrylium dye salts such as 4(4-dimethylaminostyryl) 7 hydroxy Z-phenyl
  • anti-halation dyes and pigments are those that they be readily dischargeable or dispersible in the usual photographic processing baths or optional alkaline pre-baths which may be used for the removal of the resin layer prior to development.
  • suitable fatty acid amides and mixtures thereof the following are illustrative:
  • a 0.5 to 5% by weight solution of an alkali soluble resin which is readily soluble in the usual developing agents is dissolved in a lower alkyl alcohol or mixture of such alcohols, such as methanol, ethanol, isopropanol, N- bntanol, and the like.
  • a lower alkyl alcohol or mixture of such alcohols such as methanol, ethanol, isopropanol, N- bntanol, and the like.
  • an anti-halation dye or pigment 0.2 to 4% by weight of an anti-halation dye or pigment.
  • concentration of fatty acid amide to be added to the dye solution may vary,
  • the single figure is a sectional view of a photographic film constructed according to our invention.
  • a film base has coated thereon, a layer 11 of a gelatino silver halideemulsion and on the opposite side, an alkali soluble anti-halation layer 12 containing a resin soluble in alkaline photographic processing solutions, an anti-halation dye and a fatty acid amide of from 8 to 18 carbon atoms.
