    Abstract: Photothermographic materials have increased photospeed provided by gold(III)-containing chemical sensitizers that are used combination with sulfur- and/or tellurium-containing chemical sensitizers. Increased photographic speed is achieved with minimal increase in Dmin. The gold(III)-containing chemical sensitizers are represented by the following Structure GOLD: Au(III)L′rYq GOLD wherein L′ represents the same or different ligands, each ligand comprising at least one heteroatom that is capable of forming a bond with gold, Y is an anion, r is an integer of from 1 to 8, and q is an integer of from 0 to 3.

    Abstract: A positive-acting thermographic material which is black or dark colored in the unexposed condition turns white or light colored when exposed to elevated temperatures. The material comprises a binder, a dark colored complex of ferric iron with a ligand chosen from organothiophosphorus acids, and a white organophosphorus acid or its alkali or alkaline earth metal salt. At elevated temperatures a double decomposition reaction occurs giving the light colored complex of ferric iron with the organophosphorus acid.

    Abstract: A composite structure and method therefor comprises a metal surface which is coated with a polymer incorporating a bidentate chelating functionality. The polymer provides significant and varied chemical modification to the metal surface and is useful, for example, as a protective coating or a priming layer. Bidentate chelating monomers useful in preparing homopolymers and copolymers with ethylenically-unsaturated non-chelating monomers have structures described by the formula ##STR1## in which R.sup.1 is hydrogen, lower alkyl, chlorinated lower alkyl, CN, or ClP is a connecting linkage of chain length up to to about 75 atoms, andQ is a bidentate chelating group having a high affinity for the ions of the metal of the surface involved.
