Abstract

1,186,714. Direct positive emulsions. EASTMAN KODAK CO. March 10, 1967 [March 11, 1966; Jan.17, 1967 ], No.11294/67. Heading G2C. Direct positive silver halide emulsions comprising fogged silver halide grains are characterized in that (i) an electron acceptor which spectrally sensitizes the emulsion to radiation having a wavelength longer than 480 mÁ so that the relative minus blue speed to relative blue speed of the emulsion measured by a specific process is greater than 7, is adsorbed on the surface of the silver halide grains and (ii) the grains are fogged with a reducing agent and a noble metal compound. The fogging agents and sensitizing electron acceptors are as described in Specification 1, 186, 711.
