ABSTRACT:
Holograms which contain gelatin as the binder are prepared by holographically exposing the 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 a gelatin reactive compound which has a molecular weight of over 200 and which reacts with the gelatin to form covalent bonds therewith to increase the molecular bulk of the gelatin.
