Abstract
Multilayer thermographic materials have improved adhesion between a polymeric support and film-forming polymer-containing layers disposed thereon. This improved adhesion is provided by including in the adhesion-promoting layer next to the support two or more polymers having specific properties. At least one of the polymers adheres the layer to the support, and at least one other polymer is compatible or of the same class as the film-forming polymer in the upper layer, such as a thermographic imaging layer. This adhesion-promoting layer can be provided as a very thin “carrier” layer during coating operations so that desired imaging effects and functional properties are obtained.
