Definitions

  • This invention relates to certain bulky, i.e., relatively high molecular weight, quaternary nitrogen heterocyclic compounds which function as alkali-release mordants, to photographic materials and more particularly to photographic elements containing these compounds in lightscreening and light-absorbing layers, and to methods for their preparation.
  • Such dye-mordant lightscreening salt may be in a layer overlying a light-sensitive emulsion or overlying two or more light-sensitive emulsions; or it may be in a light-sensitive emulsion for the purpose of modifying a light record in such emulsion or for protecting an overlying light-sensitive emulsion or emulsions from the action of light of wavelengths absorbed by such light-screening substance, or it may be in a layer not containing a light-sensitive substance but arranged between two light-sensitive emulsions; or it may be in a layer serving as a backing on an element having one or more light-sensitive emulsions (for example, to reduce halation).
  • light-screening substances are often required (a) in overcoatings upon photographic elements to protect the light-sensitive emulsion or emulsions from the action of light which it is not desired to record, (b) in layers arranged between differentially color sensitized emulsions, e.g., to protect redand green-sensitive emulsions from the action of blue light, and (c) in backings forming the so-called antihalation layers on either side of a transparent support carrying the light-sensitive emulsion or emulsions.
  • the element contains a color sensitized emulsion or color sensitized emulsions
  • light screening substances which can readily be rendered ineffective, i.e., decolorized or destroyed and removed prior to or during or after photographic processing. For many purposes it is particularly convenient to employ lightscreening substances which are rendered ineffective by oneof the photographic baths employed in processing the element after exposure, such as a photographic developing bath or fixing bath.
  • mordants Numerous substances have been proposed as mordants to prepare the dye-mordant salts used as light-screening and light-absorbing materials for the purposes indicated above.
  • the proposed mordants are relatively high molecular weight compounds having ionic charges opposite to those of the particular light-absorbing dye.
  • the dye employed might be an acid dye, in which case the mordant would be a cationic compound.
  • Typical of such proposed mordants are, for example, derived polymers such as the basic reaction products of polyvinylsulfonates and C-aminopyridines as described in D. D. Reynolds et al., US. Patents 2,701,243 and 2,768,- 078, granted Feb. 1, 1955, and Oct. 23, 1956, respectively.

  • a sample was treated with a fixing bath of the following composition:
  • the bleed test consisted of immersing a portion of the hand coating in stagnant, distilled water at F. for 2 minutes and inspecting for signs of dye bleeding out of the gel layer.
