Zusammenfassung:	PURPOSE:To obtain a photographic support excellent in the prevention of curling as well as in transparency and mechanical strengths. CONSTITUTION:A photographic support made from a polyester prepared from terephthalic acid, ethylene glycol and cyclohexanedimethanol as the main components, wherein the polyester contains as a comonomer component 3-20mol% aromatic dicarboxylic acid containing a metal sulfonate group based on the terephthalic acid and has a water absorption of 1.0% or more and a glass transition point (Tg) of 65 deg.C or above as measured with a differential scanning calorimeter(DSC).
