Abstract
1316335 Photographic silver halide development process FUJI PHOTO FILM CO Ltd 21 Oct 1970 [22 Oct 1969] 50071/70 Heading G2C [Also in Division C3] A silver halide photographic light-sensitive material is developed in the presence of a compound of the formula: - wherein R is H or R'CO- wherein R' is H, alkyl, substituted alkyl, heptadec-8-enyl, HOOC CH=CH- aryl or substituted aryl, x+y is a numeral of from 3 to 50, X<SP>-</SP> is an anion, and Z represents the non-metallic atoms required to complete a monocyclic heterocyclic ring. The heterocyclic ring is preferably pyridinium or imidazolium. The ratio of x:y is preferably from 2:1 to 1:5. Many compounds of the above formula are listed. The compound may be incorporated in a developing solution; pre-developement bath and/or in photographic material e.g. in an emulsion layer or an adjacent layer such as a protective layer. These compounds accelerate development and increase the sensitivity of the silver halide material, but do not produce much fog in the developed material or increase granularity of the developed image.
