Abstract: 1,164,825. Nitro dyes. L'OREAL. 29 July, 1966 [30 July, 1965 (2); 27 Jan., 1966; 4 July, 1966], No. 25277/68. Divided out of 1,164,824. Heading C4P. [Also in Division C2] Compounds of formula wherein R represents (i) a hydrogen atom or an alkyl radical of 1 to 4 carbon atoms, X represents a halogen atom, n is an integer from 2 to 6 inclusive; and A represents a substituted or unsubstituted nitrophenyl radical, substituted in para position relative to the radical by a radical of the formula NR 1 R 11 wherein R 1 and R 11 represents a hydrogen atom or an alkyl radical of 1 to 4 carbon atoms, may be used as hair dyes. They are members of a group of compounds which are used as intermediates in the preparation of nitro dyes (see Division C2).
