Abstract

The following compounds are prepared by reacting phenyl 1-hydroxy-2-naphthoate, phenyl 1-hydroxy-2-benzoate or phenyl 4-chloro-1-hydroxy-2-naphthoate as appropriate with 2-hydrazinobenzthiazole, 2-hydrazinoquinoline or 2-hydrazinopyridine as appropriate: <FORM:0935698/IV(a)/1> The following are prepared by sulphonating the corresponding unsulphonated compounds: <FORM:0935698/IV(a)/2> The compounds are all used as colour coupling agents in colour photography (see Group XX).
