Light sensitive silver halide element having photographic film base with improved curl stability

摘要

The invention contemplates a light-sensitive silver halide photographic element having at least one silver halide containing emulsion layer on a film base, the film base being a coextruded laminate having a first layer and a second layer, the first layer being a polyester of an aromatic dicarboxylic acid or a dialkyl ester thereof and an alkylene glycol adjacent to the emulsion layer, the second layer being a polyester having a humidity expansion coefficient greater than 5*10-5 (* CHEMICAL STRUCTURE *) (RH is relative humidity) and a Young's modulus at 50% relative humidity greater than 300 kPSI.
