ABSTRACT:
The present invention is photographic film base which includes a polymeric support having a first side and a second side and a glass transition temperature (Tg.sub.s). A polymeric layer is superposed on the first side of the polymeric support, the polymer layer having a glass transition temperature Tg.sub.L which is greater than the glass transition temperature of the support Tg.sub.s. The polymeric layer has a thickness of at least 2.5 percent of the thickness of the support.
