Abstract:
A method of coloring keratin fibers comprisingapplying to keratin fibers a coloring composition formed from components comprising A, at least one pyrimidine derivative of formula I â€ƒwherein R1, R2, R3 and R4 are, independently of one another, selected from hydrogen, an OH group, a NH2 group, or a NR5R6 group, wherein R5 and R6 are independently selected from a C1 to C4 alkyl group, or a C1 to C4 hydroxyalkyl group having one or more hydroxyl groups that are primary, secondary or combinations thereof, or where two of the R1, R2, R3 or R4 substituents together form a 5 or 6 member, optionally substituted, heterocycle ring containing one or two nitrogen atoms, or one or two oxygen atoms or a combination of both in the heterocycle ring, with the proviso that at least two of the R1, R2, R3 or R4 substituents are a NH2 group or NR5R6 group, and B at least one Compound selected from a m-phenylene derivatives of formula II or III â€ƒwherein R7, R8 and R11 are independently from one another hydrogen, a C1 to C4 alkyl group or a C1 to C4 hydroxyalkyl group, R9 is a C1 to C4 hydroxyalkyl group or a radical of formula IV â€ƒin which R7 and R8 are defined as above and m is an integer from 1 to 4, and R10 is hydrogen or a radical of formula V â€ƒin which R7 and R8 are as defined above and n is an integer from 1 to 4, b. m-aminophenol derivatives of formula (VI) â€ƒwherein R12 is hydrogen or a C1 to C4 alkyl group, R13 is hydrogen, fluorine, chlorine, an OCH3 group or a C1 to C4 alkyl group, R14 is hydrogen, a C1 to C4 alkyl group, a C1 to C4 hydroxyalkyl group or an OCF3 group, R15 is hydrogen, fluorine, chlorine or an OCH3 group, with the provisos that R12, R13, R14 and R15 are not hydrogen at the same time, and that, if R12 is methyl, R13, R14 and R15 are not hydrogen at the same time, c. pyridine derivatives of formula VII or VIII â€ƒwherein R16 and R17 are independently fluorine, chlorine or an OCH3 group, R18 is hydrogen, a C1 to C4 alkyl group or a C1 to C4 hydroxyalkyl group, R19 is an OH group or NH2 group, R20 is hydrogen, a C1 to C4 alkoxy group or a NH2 group, X is hydrogen or an OCH3 group, with the provisos that, if R19 is NH2, R18 and R20 are not a C1 to C4 alkyl group and a methoxy group, respectively, at the same time, and if R18 is hydrogen, R19 and R20 are not an OH group and hydrogen, respectively, at the same time, d. resorcinol derivatives of formula IX â€ƒwherein R21, R22 and R23 are independently from one another hydrogen, a C1 to C4 alkyl group or a C1 to C4 hydroxyalkyl group, with the provisos that R21, R22 and R23 are not hydrogen at the same time, R22 is not methyl if R21 and R23 are hydrogen, and R22 and R23 are not hydrogen at the same time if R21 is methyl, e. methylenedioxybenzene derivatives of formula X â€ƒwherein R24 is an OH group, a NH2 group or a NHR25 group, in which R25 is a C1 to C4 alkyl group or a C1 to C4 hydroxyalkyl, or f. 3,4-diaminobenzoic acid, and combinations thereof; and C. oxidatively developing the coloring composition using atmospheric oxygen, an enzyme containing system, or combinations thereof as the sole oxidizing agent.
