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.
Claims11
A transparent solid body having embedded in it a hologram image, and also carrying a quantity of dispersed finely-divided specular metal flakes that make the image more distinctive.
In the method of molding of a digital compact audio or video disc against a stamper containing a negative of the information the disc is to carry the improvement according to which the stamper also contains indicia which molds a hologram into the disc.
A hologram surface that is made more distinctive by a thin layer of aluminizing, in which the aluminizing is a sprayed-on layer of thin aluminum flakes from a suspension of those flakes in a vaporizable solvent.
A molded one-piece non-planar cover of a cosmetic compact having an integral transparent outer surface in which a hologram image is contained and is viewable, said cover having an inner surface that is specularly reflective.
In a process of applying a hologram to a substrate, the improvement being in enhancing the hologram by applying finely divided specularly reflective metal flakes to the substrate.
In the process of molding a plastic compact disc for storing audio or video information, the improvement comprising molding holographic image information on a face of the plastic disc simultaneously with the molding of the plastic disc.
