Abstract
A photographic polyester support having an adjacent subbing layer which comprises a polymer or copolymer of glycidyl acrylate and/or glycidyl methacrylate followed by a gelatin layer and which is annealed. Such a composite has been found to provide improved adhesion properties without chemical degradation of the subbing layer under annealing conditions.
