Abstract : Methods for manufacturing pre-holographic elements are disclosed. The methods comprise the steps of providing a poly(methyl methacrylate) base, coating the base with a nitrocellulose-containing coating composition, denitrating the coating composition, covering the coated base with water, placing a pre-hardened gelatin film under the water near the coating on the base and removing the water from between the coating and the pre-hardened gelatin film.
