Abstract
Abstract A silver halide photographic material comprising a polyester support having formed thereon at least one light-sensitive silver halide emulsion layer is disclosed, said polyester support having a glass transition temperature of from 90° to 200°C and having had at least one side thereof subjected to ultraviolet-light irradiation. The photographic material exhibits improved anticurl properties and high adhesion between the emulsion layer and the support.
