- 9. The hair colorant composition of claim 8 wherein the 1,4-diazacycloheptane derivative comprises N,N'-bis-(4-aminophenyl)-1,4-diazacycloheptane, N,N'-bis-(4-amino-2-methylphenyl)-1,4-diazacycloheptane, or N,N'-bis-(4-amino-3-methylphenyl)-1,4-diazacycloheptane.
- 10. The hair colorant composition of claim 8 further comprising a secondary intermediate and a water-containing carrier.
- 11. The hair colorant composition of claim 10 wherein the secondary intermediate is selected from the group consisting of 1-naphthol, resorcinol, 1,3-bis-(2,4-diaminophenoxy)-propane, 2-hydroxy-4-aminophenoxyethanol, 4-chlororesorcinol, 2,4-diaminophenoxyethanol, 2-methyl resorcinol, 2-methyl-5-(2-hydroxyethylamino)-phenol, and 3-amino-2-methylamino-6-methoxypyridine.
- 12. The hair colorant composition of claim 8 further comprising at least one primary intermediate in addition to said 1,4-diazacycloheptane derivative.
- 13. The hair colorant composition of claim 12 wherein the additional primary intermediate is selected from the group consisting of 2,4,5,6-tetraaminopyrimidine, 4-hydroxy-2,5,6-triaminopyrimidine, 1-(2-hydroxyethyl)-2,5-diaminobenzene, p-phenylenediamine, p-toluylenediamine, p-aminophenol, 3-methyl-p-aminophenol, 2-aminomethyl-p-aminophenol and 1,3-N,N'-bis-(2'-hydroxyethyl)-N,N'-bis-(4'-aminophenyl)-diamino-1,3-propan-2-ol.
- 14. The hair colorant composition of claim 8 comprising 0.005 to 20 percent by weight of primary intermediates and 0.005 to 20 percent by weight of secondary intermediates.
- 15. The hair colorant composition of claim 14 comprising 0.1 to 5 percent by weight of primary intermediates and 0.1 to 5 percent by weight of secondary intermediates.
- 16. The hair colorant composition of claim 8 further comprising at least one substantive dye.
- 17. A process for coloring a keratin fiber comprising contacting a keratin fiber with an oxidative colorant composition comprising a 1,4-diazacycloheptane derivative of the formula (I): ##STR5## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another represent hydrogen, a C.sub.1-4 alkyl or hydroxyalkyl group or a C.sub.2-4 dihydroxyalkyl group, X and Y independently of one another represent hydrogen, chlorine, fluorine, a C.sub.1-4 alkyl, hydroxyalkyl, aminoalkyl or alkoxy group, a C.sub.2-4 dihydroxyalkyl group or an allyl group, and R.sup.5 and R.sup.6 independently of one another represent hydrogen or a C.sub.1-4 alkyl group.
