Abstract
Abstract N-4-aminophenyl-N'-2,4-diaminophenyl alkylenediamines corresponding to the formula ##STR1## and water-soluble salts thereof. The above compounds are suitable as developers in oxidation hair dyes. Such hair dyes contain compounds corresponding to formula (I) or salts thereof as developer component in addition to conventional developer and conventional coupler components and, optionally, conventional substantive hair dyes in a cosmetic carrier. In conjunction with phenols, naphthols, resorcinols and 1,3-bis-(2,4-diaminophenyl)-alkanes or 1,3-bis-(2,4-diaminophenoxy)-alkanes as couplers, the new developers give particularly intensive colors with good light fastness properties.
