Novel coupling components |
摘要 |
Keratin fibers are colored by an agent comprising a coupler which is a m-phenylenediamine derivative of the formula (I) wherein R<SUP>1 </SUP>is a C<SUB>1</SUB>-C<SUB>4 </SUB>alkyl group or a C<SUB>1</SUB>-C<SUB>4 </SUB>monohydroxyalkyl group; R<SUP>2 </SUP>is a methyl or an ethyl group; each of R<SUP>3 </SUP>and R<SUP>4 </SUP>is independently a branched or unbranched C<SUB>2</SUB>-C<SUB>6 </SUB>hydroxyalkyl group; and a cosmetically acceptable carrier. These couplers exhibit improved toxicological and dermatological properties and permit hair colorations in a broad color spectrum with good fastness properties.
