ABSTRACT:
Multicolor holograms using gelatin as the binder and having interference fringes lying in layers parallel to the substrate, the colors of which are visible by reflection in incident natural light, by treating the holographic material which has been holographically exposed and processed to produce a hologram therein, by applying to the selected areas of the gelatin which contains the interference fringes a solution of a compound which causes the interference fringes to separate permanently and produce a bathochromic shift in the replay wavelength.
