Abstract

1,151,230. Covered grain silver halide emulsions. EASTMAN KODAK CO. Aug.24, 1966 [Aug. 27, 1965], No.37940/66. Heading G2C. The invention relates to covered grain emulsions as described in Specification 1, 011, 062 with a chemically sensitized central core in which the surface of the outer shell has been sensitized with a noble metal, sulphur and/or reduction sensitizer and the central core has been sensitized with a sulphur sensitizer and a reduction sensitizer e.g. sodium thiosulphate and triethylene tetramine.
