Abstract
This invention describes a method for manufacturing a photographic support which includes providing a support and laminating a surface of the support with a polymer resin formulation containing from 0.001 to 1 weight percent antioxidant at a temperature of from 305.degree. to 360.degree. C. while exposing the polymer resin formulation to an ozone containing gas at a rate of greater than 0.1 mg/m.sup.2 of said support.
