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:
This invention encompasses preparations containing hair dyes of the formula ##STR1## wherein: one of R.sup.1 or R.sup.2 is a nitro and the other is --SO.sub.3 H;one of R.sup.3 or R.sup.4 is --NR.sup.6 R.sup.7 and the other is hydrogen, chlorine, or a C.sub.1-4 alkyl, and R.sup.6 and R.sup.7 are independently hydrogen, C.sub.1-4 alkyl, or C.sub.2-4 hydroxyalkyl; andR.sup.5 is hydrogen, chlorine, or a C.sub.1-4 alkyl;or a water soluble salt thereof; certain novel compounds within the above formula; and a method for dyeing hair.
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:
This invention is directed to compositions of the developer-coupler type of the dyeing of hair, consisting essentially of substituted dihydroxypyridine compounds or salts thereof as coupling components and, as developer components, the conventional components used in oxidation dyes.
摘要:
Novel substituted nitrodiphenylamines and substantive hair dye preparations containing them or containing nitrodiphenylamines with different substituents. The dyes result in yellow to copper-colored shades of high intensity and fastness and are more soluble in water than known nitroanilines dyes.
摘要:
This invention is directed to bis-(2,4-diaminophenoxy)-alkanols and salts thereof and to compositions of the developer-coupler type for the dyeing of hair, consisting essentially of bis-(2,4-diaminophenoxy)-alkanols or salts thereof as coupling components and, as developer components, the conventional components used in oxidation dyes.
摘要:
Meto-aminophenols of the formula ##STR1## where R is hydrogen, C.sub.1-4 -alkyl, or a C.sub.2-4 -hydroxyalkyl; and their use as couplers in an oxidative hair dye in combination with developers.
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.
摘要:
This invention encompasses compounds of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently are hydrogen, C.sub.1-4 alkyl, or C.sub.2-4 hydroxyalkyl; one of R.sup.3 to R.sup.7 is --SO.sub.3 H or --COOH; and the remaining of R.sup.3 to R.sup.7 independently are hydrogen, chlorine, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, or --NR.sup.8 R.sup.9, where R.sup.8 and R.sup.9 independently are hydrogen, C.sub.1-4 alkyl, C.sub.2-4 alkoxy, or where --NR.sup.8 R.sup.9 is piperidine, morpholine, piperazine, or pyrrolidone; or a water soluble salt thereof; hair dye preparation containing these compounds, and methods for dyeing hair using such preparation.
