Definitions

  • This invention relates to novel polymeric compounds.
  • this invention relates to novel polymeric compounds which are good mordants for dyes used in photographic systems.
  • this invention relates to elements containing said polymers which are useful in photographic systems.
  • mordants have been used as mordants in imbibition printing and in color photographic products etc. to prevent migration of dyes.
  • mordants that have been employed are polymers containing acid salts such as are disclosed in U.S. Pat. No. 3,048,487 and U.S. Pat. No. 3,184,309 both to Hyman L. Cohen and Louis M. Minsk.
  • Mordants of these types exhibit good dye retention under certain conditions.
  • these mordants can diffuse out of the blanks in which they are used and into the matrix when contacted therewith. The result is that as repeated dye transfers are made from a given matrix more mordant diffuses into the matrix, combines with some of the dye and is held there.
  • the mordant-dye complex formed in the matrix increases with successive transfers, finally reaching a point where it interferes with the transfer process so that satisfactory images cannot be made. It thus becomes necessary to subject the matrix to a special treatment between transfers thereby increasing the cost of the process. This special treatment, in addition to its cost, very often has a deleterious effect upon the image quality-definition, for example. Thus, it is desirable to provide a mordant which is substantially free of matrix poisoning.
  • It is a further object to provide a photographic element comprising a support, a silver halide layer and at least one layer which comprises a polymer of this invention.
  • Another object is to provide a silver halide emulsion containing the polymer of this composition.

  • the aryl or aralkyl group-substituted polymers of the invention have been found to be superior mordants. While definition may or may not be affected, matrix poisoning and stain are greatly reduced.
  • matrix staining or poisoning bears a direct relationship to the average number of aryl or aralkyl groups per nitrogen atom in the carbon portion of the copolymers of the invention.
  • the matrix stain or poisoning decreases.
  • the greater the average number of aryl or aralkyl groups per quaternized nitrogen atom in the cation portion of the aryl or aralkyl-substituted, quaternized nitrogen containing interpolymers the more effective the mordant from the standpoint of matrix stain or poisoning prevention.
  • the only limitation placed on the number of aryl or aralkyl groups per nitrogen atoms present in the copolymer is that dictated by water or methanol solubility and compatibility with the hydrophilic colloids.
  • Preferred polymers according to this invention comprise units of the following formula in copolymerized relationship with units of at least one other ethylenically unsaturated monomer.

  • the polymers should be substantially free of carboxy groups for the presence of carboxy groups in the interpolymers interferes with effective dye mordanting.
  • aromatic nuclei can be located on any unit of the polymeric chain as long as there are two aromatic nuclei for each quaternized nitrogen atom in said polymer.
  • at least one of R R or R in the above formula contain an aromatic nucleus.
  • the aromatic nuclei contain at least, 5 carbon atoms often 5-12 carbon atoms and can be represented by the structure:
