Carbodiimide Hardening of Gelatin

Paper presented at a symposium on “Photographic Gelatin”, organized by the Science Committee of the Royal Photographic Society on 19–22 September 1963 in Cambridge, England.

Abstract

Carbodiimides con rapidly and effectively crosslink gelatin solutions and films. By proper choice of gelatin concentration and pH, these fast acting hardeners can be incorporated in gelatin solutions which have stable viscosity and can be cast into films which rapidly harden without after-hardening. Carbodiimides are attractive os hardeners for gelatin—silver halide photographic emulsions.
