Abstract (en)
[origin: CA1155440A] A PROCESS FOR THE CHAIN-LENGTHENING OF GELATINE ( ) In a process for the chain-lengthening of gelatine the gelatine is brought into contact with a fast-acting cross-linking agent which can activate the carboxyl groups of the gelatine. The result is a chain-lengthened gelatine which has advantageous properties for the production of photographic layers. A-G 1587
