Abstract
1351038 Hardening gelatine FUJI PHOTO FILM CO Ltd 27 Sept 1971 [30 Sept 1970] 44995/71 Heading C3H [Also in Division G2] Gelatine layers such as photographic emulsion or auxiliary layers are hardened by incorporating into the coating composition therefor a reactive halogen hardener, a reactive vinyl group hardener or a carbodiimide hardener and a salt of Na, K, Li, Mg, Ca or Ba and a volatile organic carboxylic acid such as formic acid, acetic acid or propionic acid, or carbonic acid, and drying the layer. Hardeners specified include dichlorotriazines, triacrylyltriazines, trisvinylsulphonyl-1 : 3 : 5-hexahydrotriazine, methylene-bis-acrylamide, methylene-bis-maleimide and n-propyl-allyl-carbodiimide.
