Abstract
A polyester support having an adjacent subbing layer which comprises a polymer or copolymer of glycidyl acrylate and/or glycidyl methacrylate improves the adhesion of a photothermographic imaging layer containing a poly(vinyl butyral) binder coated from an organic solvent. The subbing layer can be applied in the form of an aqueous dispersion in the prescence of a coalescing agent. Such a subbing layer does not adversely affect sensitometry in a photothermographic or thermographic element.
