Abstract

1,244,566. Photographic silver halide emulsions. FUJI PHOTO FILM CO. Ltd. June 19, 1969 [June 19, 1968], No. 31104/69. Heading G2C. A photographic silver halide emulsion is increased in speed by the presence therein of a monocyclic alicyclic compound having 4 or more atoms in the ring and containing 2 or 3 hydroxyl groups in the ring or in a side chain. Compounds specified are 1: 2-cyclopentanediol, 1: 2- cyclobutanediol, 1-methyl-2: 3-cyclopentanediol, 1:3-cyclopentanediol, 2-hydroxymethyl -cyclopentanol, 1: 2-, 1: 3 and 1:4-cis- and 1:4-transcyclohexanediol, 1:4-cyclohexanedimethanol, 1-methyl-1: 2-cyclohexanediol, 2-hydroxymethyl -cyclohexanol and 1:3:5-cyclohexanetriol, and they may be added during the chemical ripening step. The compound also has an antifoggant effect.
