Abstract : A method for manufacturing large, nonplanar, transparent, gelatin-coated polymer sheets is disclosed. These sheets when sensitized, exposed, and developed can record and display holograms. A poly(methyl methacrylate) sheet is coated with nitrocellulose, the nitrocellulose is denitrated, and a gelatin solution is applied, then hardened. The sheet with its gelatin film is then thermally formed to any desired three-dimensional configuration. (Author)
