Abstract

Compounds of formula <FORM:1122905/C2/1> wherein X is halogen, alkyl, trifluoromethyl, alkoxy, aryloxy or acylamino (e.g. carboxylic amido or sulphamino) group, Y is hydrogen or a group listed under X, and Z is a halogen or hydrogen atom, are used as photographic colour couplers (see Division G2-G3). 2-Methyl-benzoyl-aceto-(21-chloro)anilide is prepared by heating equimolar amounts of o-chloroaniline and the ethyl ester of 2-methyl-benzoylacetic acid; the corresponding 2-methyl-21 - fluoro, 4 - methyl - 21 - fluoro, 2 - methyl - 21 - ethoxy, 2 - methyl - 41 - (411 - toluenesulphamido) and 3 - methyl - 21 - methoxy derivatives are prepared similarly.
