Nitroparaphenylene diamine derivatives and methods of making them
Abstract
Abstract in which n is a whole number between two and six inclusive, while R2 and R3 represent H, a lower alkyl, or a lower hydroxyalkyl, and the alkyl portion of R R''''R1 R2 and R4 having 1 to 6 carbon atoms. Some of these derivatives are new compounds, and the invention includes new hair dyeing compositions comprising such compounds and the method of applying them to the hair. RADICAL IN WHICH R'' represents H, methyl, or NO2, or an OC-R'''' radical in which R'''' represents a lower alkyl; AND AT LEAST ONE OF R and Z is H; R1 represents a lower alkyl, lower hydroxyalkyl, lower alkoxyalkyl or IN WHICH: R represents H or a lower alkyl; Z represents H, an Methods of making nitroparaphenylene diamine derivatives responding to the formula:
