films which are usable visually but do not have any density requirements for printing onto ultraviolet-sensitive materials

storage conditions suitable for the preservation of recorded information for a minimum of 10 years

image or image-forming layers(s) of photographic films, papers, and plates

polyester base for recording materials composed mainly of a polymer of ethylene glycol and terephthalic acid

plastic support for the emulsion and backing layers

optical density in which the incident radiant flux has the same spectral energy distribution as the printer light source and the transmitted density is evaluated by a receiver having the same spectral response as the print material

optical density of a processed photographic image in which the incident radiant flux has a spectral energy distribution as defined in ISO 5-3, and the transmitted or reflected flux is evaluated by the human eye or by a receiver having the same spectral receiver as the human eye

recording material that can be expected to retain information forever so that such information can be retrieved without significant loss when properly stored

length of time that information is predicted to be acceptable in a system after dark storage at 23 °C and 50 % RH

films which are usable both visually and for printing onto ultraviolet-sensitive materials
