(57) [Summary] [Structure] A photographic support comprising a copolyester having polyethylene terephthalate as a main component, wherein the copolyester has a copolymer component having at least a metal sulfonate group as all ester bond units. On the other hand, 2 ˜7 mol% and 0.01 to 2.0 wt% of an antioxidant with respect to the copolymerized polyester. In a preferred embodiment of the present invention, the photographic support comprises a copolyester having polyethylene terephthalate as a main component, and a molecular weight of 600 based on the total weight of the copolyester of 3 to 10 wt%. To 20,000 polyalkylene glycols, and the antioxidant is a hindered phenol compound or a mixture of a hindered phenol compound and an allylamine compound. [Effect] It was possible to provide a photographic support which is excellent in curl curl elimination and does not adversely affect photographic performance. |
