| 摘要 |
<p>The invention relates to combinations consisting of a compound (I), wherein R represents a C1-4 alkyl radical or a C2-4 hydroxy alkyl radical or a C2-4 aminoalkyl radical and R<1> stands for a hydrogen atom, a halogen atom or a C1-4 alkyl radical and X represents a -(CH2)n-or -(CH2)n-or -CHOH-(CH2)n-group, wherein n is a whole number ranging from 0-4, or of a physiologically salt of (1) with a pyrimidine derivative with 2-4 amino substituents and 0-2 hydroxy substituents on a pyrimidine ring or a physiologically compatible salt thereof. The inventive compounds are highly suitable as developer components in oxidation colouring agents for dyeing keratin fibres. Combinations containing N,N'-Bis-( beta -hydroxy-ethyl)-N,N'-bis-(4-aminophenyl)-1,3-diamino-propane-2-ol are particularly suitable in this respect.</p> |
