Abstract

Abstract The present invention provides a recording material comprising a substrate and a recording layer thereon where the oxygen transmission rate of the substrate, as measured in accordance with Method B of JIS K 7126, is not greater than 50 cc/m 2 /day. If necessary, a protective layer is formed on the recording layer. The substrate (21) is composed of a sheet of base paper and a plastic film layer present at least on the side of the paper which faces a recording layer to be formed. The plastic film layer is appropriately selected from the group consisting of a polyester film, a polyvinylidene chloride film, a polycarbonate film, a polyvinylchloride film and a film of a random copolymer of ethylene and vinylalcohol. The recording material according to the present invention is excellent in the long-term preservation of images, fading resistance and light fastness.
