Abstract
Abstract A photographic material which exhibits excellent dynamic properties and little curl is provided. The silver halide photographic material comprises at least one light-sensitive layer on a polyester support, wherein the polyester support is a polyester support having a glass transition temperature of 90 °C to 200 °C and is subject to glow discharge treatment. The polyester support is preferably subjected to post heat treatment at a temperature ranging from 50 °C to lower than the glass transition temperature of said polyester support after the glow discharge treatment.
