Abstract
Holograms are formed in moldable materials of varied shapes and curvatures utilizing injection molding and the like. Instead of the conventional metallizing, there can be sprayed on flakes of highly specular metal made by breaking up a thin coating of metal metallized by conventional metallizing on a removable support. Hologram on one surface of a molding that has a 100% mirror on an opposing surface, is suitable for cosmetic compact case covers or the like. Holograms can also be applied to digital compact audio discs or video discs.
