ABSTRACT:
A polyester film which has the in-plane rate of dimensional change of more than 0.02%, but not more than 0.05%, when the film is kept for 72 hours under the conditions of temperature 60.degree. C. and relative humidity 80%, and the average value of the in-plane rate of dimensional change of from -0.07% to 0.03% and the in-plane anisotropy of the in-plane rate of dimensional change of from 0% to 0.08%, when the film is kept for 30 minutes at a temperature of 105.degree. C. This polyester film is low in heat shrinkage and excellent in thermal dimensional stability. A heat-development, photographic light-sensitive material using the polyester film is low in heat shrinkage and excellent in thermal dimensional stability.
