Indoaniline having the formula ##SPC1## Wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each independently represent a member selected from the group consisting of hydrogen, lower alkyl or halogen with 1 - 2 of these substituents being other than hydrogen; R.sub.5, R.sub.6 and R.sub.7 each independently represent a member selected from the group consisting of hydrogen, lower alkyl and lower alkoxy; R.sub.8 and R.sub.9 each independently represent a member selected from the group consisting of hydrogen, lower alkyl and lower alkyl substituted with a member selected from the group consisting of amino, hydroxy, carbamoyl, piperidinyl and acylamino, R.sub.8 and R.sub.5 or R.sub.9 and R.sub.6 being able to form with the adjacent nitrogen atom a dihydro-oxazine or pyrroline heterocycle; Z represents a member selected from the group consisting of amino, acylamino and hydroxy, and the salts formed by these indoanilines with organic or inorganic acids, in particular, their acetates, oxalates, hydrochlorides, hydrobromides, persulfates, perchlorates and the double zinc salts of these compounds, which can, of course, be in a tautomeric form of that represented by the above formula. These indoanilines are usefully employed for dyeing keratinous fibers, and, in particular, human hair.
Indoaniline的化学式为## SPC1 ##,其中R.sub.1,R.sub.2,R.sub.3和R.sub.4各自独立地代表从氢,较低的烷基或卤素中选择的成员,其中1-2个取代基不是氢; R.sub.5,R.sub.6和R.sub.7各自独立地代表从氢,较低的烷基和较低的烷氧基中选择的成员; R.sub.8和R.sub.9各自独立地代表从氢,较低的烷基和被从氨基,羟基,氨基甲酰基,哌啶基和酰胺基中选择的成员取代的较低烷基,其中R.sub.8和R.sub.5或R.sub.9和R.sub.6能够与相邻的氮原子形成二氢噁唑或吡咯烷杂环; Z代表从氨基,酰胺基和羟基中选择的成员,以及这些indoanilines与有机或无机酸形成的盐,特别是它们的乙酸盐,草酸盐,盐酸盐,溴化盐,过硫酸盐,高氯酸盐和这些化合物的双锌盐,当然,它们可以处于上述化学式所代表的互变异构体形式。这些indoanilines可用于染色角蛋白质纤维,特别是人类头发。
