Abstract
A polyester film is disclosed, exhibiting a minimum value of not more than 0.15 with respect to the tan &dgr; value obtained at a frequency of 0.01 Hz within the range of 100 to 160° C., the tan &dgr; being determined in a tensile viscoelasticity measurement. A photographic support and photothermographic material using this polyester film are also disclosed, which exhibits superior dimensional stability even when subjected to thermal development at a high temperature and little roll set curl when used in a roll form.
