摘要： Cyanine dyes are disclosed having a nucleus of the formula: ##STR1## wherein; A and B are independently selected from the group consisting of heterocyclic ring nuclei and heterocyclic fused ring nuclei so as to complete a cyanine dye,m and n independently have values of 0, 1, 2 or 3 with the proviso that 2.ltoreq.m+n.ltoreq.4,R is selected from the group consisting of hydrogen, alkyl groups and aryl groups, each of which groups may be substituted, andQ represents those non-metallic atoms necessary to complete a nucleus selected from the group consisting of heterocyclic ring nuclei, carbocyclic ring nuclei, heterocyclic fused ring nuclei and carbocyclic fused ring nuclei.The cyanine dyes of formula (I) may be used to spectrally sensitise silver halide grains to radiation in the wavelength range from 650 nm upwards, especially 700 to 850 nm, to provide infrared-sensitive, silver halide photographic materials which are particularly suitable for use with electronically modulated exposure sources, such as lasers and light emitting diodes.

摘要： Pepper fog may be reduced in high contrast photographic materials comprising silver halide emulsion in association with a hydrazine by the presence of at least 0.001 mole per mole of silver halide of a water-soluble bromide and/or water-soluble chloride. Suitable water-soluble bromides and chlorides are alkali metal bromides and chlorides which are advantageously added to the silver halide emulsion after physical ripening and washing.
