<p>New (2,4-diaminophenoxy)-alkylamines have formula (I), (where R is -(CH2)n-NR1R2 or -CHMeCH2-NR1R2, in which n is integer 1-5; each R1 and R2 is 1-4 C-alkyl, or R1 and R2, together with the N atom, for a morpholine, piperidine or pyrrolidine ring). (I), and their salts with organic or inorganic acids, are used as coupler components in oxidn. hair dyes. (I) form strong, fast brown to black and blue shades; are soluble in water, resist storage, are non-toxic and cause no skin-irritation.</p> |
