Definitions

  • Multilayer color films of the incorporated coupler type are stabilized so as to maintain their sensitometric properties during storage by hardening the emulsion layers with an aldehydic gelatin hardener such as sucoinaldehyde bis-bisulfite, neutralizing unreacted hardener with, for example, hydroxylamine sulfate, treating the emulsion layers with bromide salt solution and drying the film.

Abstract

MULTILAYER COLOR FILMS OF THE INCORPORATED COUPLER TYPE ARE STABILIZED SO AS TO MAINTAIN THEIR SENSITOMETRIC PROPERTIES DURING STORAGE BY HARDENING THE EMULSION LAYERS WITH AN ALDEHYDIC GELATIN HARDENER SUCH AS SUCCINALDEHYDE BIS-BISULFITE, NEUTRALIZING UNREACTED HARDENER WITH, FOR EXAMPLE, HYDROXYLAMINE SULFATE, TREATING THE EMULSION LAYERS WITH BROMIDE SALT SOLUTION AND DRYING THE FILM.
