Abstract

Gelatine derivatives are prepared by reacting gelatine at a pH of 8 or more with heterocyclic nitrogen compounds having a 5- or 6-membered ring and a chlorine or bromine atom substituted on a ring carbon atom which is vicinal to the nitrogen atom. Heterocyclic compounds referred to are 2-chlorobenzthiazole and halogen substituted pyrimidines and triazines, especially those containing a carboxy or sulpho group. Specifications 649,545 and 822,047 are referred to.
