Novel compounds of the general formula ##STR1## wherein Z represents a substituted lower alkyl radical; each of R.sub.1 and R.sub.2 is hydrogen atom, a lower alkyl or a substituted lower alkyl identical with or different from Z and the functional groups NO.sub.2 and NR.sub.1 R.sub.2 can occupy all ring positions in relation to OZ, with the exception that if Z is .beta.-hydroxyethyl, --NO.sub.2 is in the 4 position and --N(R.sub.1)(R.sub.2) is in the 2 position then either R.sub.1 or R.sub.2 is other than hydrogen. The novel compounds are for dyeing human hair in a variety of yellow shades. The compounds of formula (I) may be used as aqueous or water-alcohol solutions to form dye compositions for dyeing human hair.
通用公式##STR1##中的新化合物,其中Z代表取代的较低烷基基团;R.sub.1和R.sub.2中的每一个是氢原子、较低烷基或与Z相同或不同的取代较低烷基,功能基团NO.sub.2和NR.sub.1 R.sub.2可以占据相对于OZ的所有环位置,但如果Z为β-羟乙基,则--NO.sub.2位于4位,--N(R.sub.1)(R.sub.2)位于2位,则R.sub.1或R.sub.2中的一个不是氢。这些新化合物用于染色人类头发,产生各种黄色调。公式(I)的化合物可用作水性或水醇溶液,用于制备染色人类头发的染料组合物。
