PURPOSE:To provide the photographic polyester type support insusceptible to winding tendency at the time of heat treatment and good in planeness. CONSTITUTION:The photosensitive material is obtained by forming at least one photosensitive layer on a polyester film support, and this polyester film support is characterized by having a glass transition point of 90-200 deg.C, and being heat-treated in the temp-range from 50 deg.C to its glass transition point during the time from its film-forming to application of a photosensitive layer by using a winding core having a modulus of elasticity of >=500,000kg/cm<2> and coated with a material having that of <=50,000kg/cm<2>. |
