Abstract
Thermographic and photothermographic materials comprise a surface barrier layer to provide physical protection and to prevent migration of diffusible imaging components and by-products resulting from high temperature development. The barrier layer comprises a film-forming acrylate or methacrylate polymer(s) that has a molecular weight of at least 8000 g/mole and comprises epoxy functionality and is capable of retarding diffusion of mobile chemicals such as fatty acids. This polymer is preferably present in admixture with at least one other film-forming polymer to provide a clear and scratch-resistance surface film.
