Abstract: A process for forming a conductive substrate comprises coating onto a polyethylene terephthalate substrate an aqueous coating solution containing a conductive crosslinkable polymer with charge carrying groups such as sulfonic acid, sulfuric acid ester or quaternary ammonium salt groups attached to a polymerized ethylenic monomer backbone, a volatile amine in an amount to maintain a pH of above 7.0 and a crosslinking agent such as a polyfunctional aziridine, removing water and the volatile amine which decreases the pH to below 7.0 wherein a reaction between the crosslinkable groups of the polymer and the crosslinking agent is initiated to form a crosslinked conductive polymer film.

Abstract: A conductive substrate for use in a photographic element comprises a polyethylene terephthalate support coated with 0.01-10 g/m.sup.2 of a conductive layer having a low surface energy during coating and a high surface energy after coating which is the reaction product of (i) a conductive crosslinkable polymer with charge carrying groups such as sulfonic acid groups, (ii) a volatile amine and (iii) a crosslinking agent such as a polyfunctional aziridine.

Abstract: Improved image receiving elements for nonimpact printing comprising a support and an image receiving layer, said image receiving layer comprising a whitening agent and a binder, said binder consisting essentially of 10-25% gelatin and 75-90% water soluble, film forming acrylic polymer are disclosed.

Abstract: Desensitization defects due to nonferrous metal contamination of a silver halide film sensitized by a cysteine-thiazolidine moiety are decreased by incorporating a chelating agent such as quinaldic or picolinic acid into one or more layers of the film.
