    摘要: Process for the temporary dyeing of keratinous fibers with a composition containing an insoluble pigment obtained by the oxidative polymerization of an indole compound of formula (I) ##STR1## in which R.sup.1 and R.sup.3 are hydrogen or alkyl; R.sup.2 is hydrogen, alkyl carboxyl or alkoxy carbonyl; R.sup.4 and R.sup.7 are hydrogen, hydroxy, alkyl, amino, alkoxy, acyloxy or acylamino; R.sup.5 is hydrogen, hydroxy, alkoxy, alkyl, halogen, amino, acyloxy, acylamino or trimethylsilyloxy; R.sup.6 is hydrogen, hydroxy, alkoxy, amino, acyloxy, acylamino, trimethylsilyloxy or hydroxyalkylamino; R.sup.5 and R.sup.6 can also form, together with the carbon atoms to which they are attached, a carbonyl-dioxy ring; at least one of the radicals R.sup.4 to R.sup.7 is an OZ or NHR.sup.8 grouping, the R.sup.8 radical of the NHR.sup.8 grouping being hydrogen, acyl or hydroxyalkyl and the Z radical of the OZ grouping being hydrogen, acyl, alkyl or a trimethylsilyl group.
