    摘要: New 2,4,5,6-tetra-aminopyrimidine derivatives corresponding to the following general formula ##STR1## in which R.sup.1 is a group of the formula --NH--(CH.sub.2).sub.n --NH--, where n=2-4, a group of the formula --NH--CH.sub.2 --CH(OH)--CH.sub.2 --NH-- or a group of the formula ##STR2## R.sup.2 and R.sup.3 independently of one another represent hydrogen, chlorine or a group of the formula --OR.sup.4 where R.sup.4 is a C.sub.1 -C.sub.4 alkyl group and A is a CH group or a nitrogen atom, and salts thereof. The compounds are suitable as developer components for oxidation hair dyes which, in conjunction with a number of standard coupler compounds, form a wide range of brilliant colors with high absorptive power on human hair and good fastness properties.

    摘要: Hair-dyeing compositions containing oxidation dye precursors and a carrier contain coupler components corresponding to the formula: ##STR1## wherein R.sup.1 is selected from the group consisting of hydrogen, a C.sub.1 -C.sub.4 alkyl group or a halogen atom; R.sup.2 and R.sup.3 independently of one another are selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl groups or C.sub.2 -C.sub.4 hydroxyalkyl groups, or together with the nitrogen atom, form a morpholine, piperidine, pyrrolidine or piperazine ring; and R.sup.4 is selected from the group consisting of hydrogen or a --NR.sup.2 R.sup.3 group; or salts thereof. The composition also contains typical developer components. The compounds are particularly suitable as red couplers for developers of the 2,4,5,6-tetraaminopyrimidine type, including derivatives thereof.

    摘要: 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.
