ABSTRACT:
A thermally processable imaging element having a hydrophobic imaging layer, an adhesion promoting polymer layer and an overcoat layer comprising poly(silicic acid) provides improved adhesion of the overcoat layer during thermal processing. The adhesion promoting layer comprises a terpolymer that promotes adhesion between the hydrophobic imaging layer and the overcoat layer without adversely affecting sensitometric properties of the imaging element. The adhesion promoting layer is useful in photothermographic and thermographic elements and processes.
