ABSTRACT:
Water-soluble substituted and unsubstituted triamino C.sub.1-4 -alkoxy pyrimidines are effective dyes for hair when oxidized in conjunction with a coupling agent. The oxidation can be performed at alkaline pH at room temperature, with air, and provides long-lasting and light-fast dyeings over a broad color range.
