Abstract
Abstract PCT No. PCT/EP85/00222 Sec. 371 Date Dec. 12, 1985 Sec. 102(e) Date Dec. 12, 1985 PCT Filed May 13, 1985 PCT Pub. No. WO86/00303 PCT Pub. Date Jan. 16, 1986.Novel 2-alkyl sulfonyl ethyl-1,4-diaminobenzenes of formula 1 <IMAGE> (I) wherein R denotes CH3 or C2H5 and the salts thereof, a process for making the compositions of formula I as well as compositions for the oxidative dyeing of human hair upon the basis of a developing substance-coupler substance-combination with a content of a composition of formula I as developing substance. The well water soluble developing substances of the formula I result in very natural appearing blond to brown color shades in combination with the coupler substances resorcinol, 4-chororesorcinol,4,6-dichlororesorcinol, 4-hydroxy-1,2-methylenedioxybenzene and 4-amino-1,2-methylenedioxybenzene.
