Abstract
Abstract A laminate to extend the life of photographs and prevent them from gradual deterioration due to environmental conditions comprises a laminate made of a transparent film of ultraviolet-stabilized polyethylene terephthalate or ultraviolet-stabilized acrylonitrile and a transparent silicone or acrylic adhesive bonded to the film, the laminate being adapted to be bonded to the image surface of a photograph by the adhesive. Alternatively, to provide even greater protection against moisture vapor and oxidation, an additional layer of a transparent fluorocarbon polymer may be bonded to the ultraviolet-stabilized polyethylene terephthalate or ultraviolet-stabilized acrylonitrile with a silicone or acrylic adhesive. Alternately, to provide a better aesthetic appearance by means of thermal texturization, an ultraviolet-absorbing polymethylmethacrylate film may be bonded to the ultraviolet-stabilized polyethylene terephthalate or ultraviolet-stabilized acrylonitrile with a silicone or acrylic adhesive. Any of these combinations is effective to protect photographs over a long period of time from elements which cause fading and degradation, such as ultraviolet radiation, cycling relative humidity, atmospheric pollution and oxidation.
