Abstract: Thermally processable imaging elements in which the image is formed by imagewise heating or by imagewise exposure to light followed by uniform heating are comprised of a support, a thermographic or photothermographic imaging layer, a protective overcoat layer which is an outermost layer on the same side of the support as the imaging layer, a backing layer which is an outermost layer on the side of the support opposite to the imaging layer, and an electroconductive agent in at least one layer of the element. Each of the protective overcoat layer and the backing layer contains a fluorosurfactant in an amount sufficient to serve as a triboelectric charge control agent and effective in providing essentially the same triboelectric charging characteristics to the backing layer as to the protective overcoat layer.

Abstract: A black and white photographic element contains a filter dye of Formula (I): ##STR1## wherein each R.sup.1 is independently substituted or unsubstituted alkyl, substituted or unsubstituted alkoxy, cyano, hydroxy, carboxy, substituted or unsubstituted amido, or substituted or unsubstituted sulfonamido;n is 1-4;R.sup.2 is H, substituted or unsubstituted alkyl or amido;each of R.sup.3 and R.sup.4 is independently hydrogen or substituted or unsubstituted alkyl; andM is a cation.

Abstract: Thermally processable imaging elements in which the image is formed by imagewise heating or by imagewise exposure to light followed by uniform heating are comprised of a support, a thermographic or photothermographic imaging layer, a protective overcoat layer and a backing layer and include in at least one layer thereof, polymeric matte particles comprising a polymeric core surrounded by a layer of colloidal inorganic particles. The polymeric matte particles provide enhanced image quality and improved processing characteristics with respect to adhesion, dusting and lack of haze.
