ABSTRACT:
Holograms which contain gelatin as the binder are prepared by holographically exposing the holographic material by use of coherent light, developing the holographic image by a chemical or physical process and before processing, simultaneously or subsequently, treating the material with a solution of an onium compound which comprises at least one alkyl group having from 10 to 18 carbon atoms or in which the total number of carbon atoms in the substituent group is at least 15 or a polymeric compound which comprises at least one onium group in the repeating unit.
