Abstract
Abstract A moisture and oxygen barrier laminate which can be applied to a surface of photographic or printed material. The laminate also has an adhesive layer containing ultraviolet light absorbers therein. In the one embodiment, the laminate is transparent, thus allowing continuous display of a photographic or printed material. In another embodiment, the multilayer device is opaque, thus completely blocking the transmission of both ultraviolet and visible light to the photographic film or print. In the latter embodiment, the multi-layer device is removed for display of the photographic print or film and subsequently reattached during storage.
