Abstract From the Canadian patent

Abstract of the Disclosure, A photographic element comprising a support having thereon at least one silver halide emulsion layer having associated therewith a dye-forming coupler and an organosilane, nonhydrolyzable in an alkaline medium, wherein:, (a) one or two aryloxy groups are attached to the silicon atom of the silane either directly or indirectly through an alkylene group or an alkyleneoxy group, and, (b) each aryloxy group is attached directly or indirectly through a single linking group to an aryl group substituted with a hydroxy, hydroxyalkoxy organosilyloxy, organosilylalkoxy, or organosilyloxyalkoxy group.
