Abstract
A overcoat layer comprising poly(silicic acid) ##STR1## on a thermally processable element enables reduced release of volatile components from the element during thermal processing. The overcoat layer also can optionally comprise other water soluble polymers. A developed visible image is provided in an exposed silver halide photothermographic element comprising such an overcoat by uniformly heating the photothermographic element to moderately elevated temperatures without release of volatile components. The described overcoat is also useful on thermographic elements.
