| titleOfInvention | Direct-positive silver halide photographic material |
| abstract | Direct positive silver halide photographic materials comprising a support, a silver halide emulsion layer comprising fogged silver halide particles prepared in the presence of a water soluble iridium salt or a water soluble rhodium salt, and a hydrophilic colloidal layer comprising (a) a compound selected from Formula I and II and (b) at least one compound selected from the group consisting of Formula III and a gold compound, said Formula I being <IMAGE> wherein R1 is hydrogen, alkyl, -SO3M, or -COOM, wherein M is selected from hydrogen, alkali metals, and ammonium, and R2 is selected from hydrogen and lower alkyls, said Formula II being <IMAGE> wherein R3 is selected from hydrogen, alkyl, -SO3M, and -COOM, and R4 is selected from hydrogen, alkyl, and -CH2-S-(CH2)n-Y', wherein n is an integer of from 1 to 3, and Y' is selected from hydrogen and -SO3M, and said Formula III being H2N-Y-NH-Y]mNH2 wherein m is an integer of from 1 to 5 and Y is an alkylene radical having from 2 to 4 carbon atoms, provided at least two Y groups present within the same molecule are different alkylene radicals. |
