Abstract
Abstract A dye composition for keratinic fibers comprises an aqueous alcoholic solution of an indoaniline selected from (a) one having the formula <IMAGE> wherein Z is selected from amino, acetylamino and hydroxy; R5, R6 and R7 each independently are selected from hydrogen, lower alkyl having 1-6 carbon atoms and lower alkoxy having 1-6 carbon atoms; R8 is selected from hydrogen, lower alkyl having 1-6 carbon atoms and together with R5 and the nitrogen atom to which R8 is attached form dihydro-paroxazine; and R9 is selected from hydrogen, lower alkyl having 1-6 carbon atoms and together with R6 and the nitrogen atom to which R9 is attached form dihydro-paroxazine, with the proviso that at least two of R5, R6, R7, R8 and R9 are other than hydrogen when Z is NH2 and that only one of R8 and R9 form dihydro-paroxazine; (b) an acid salt of said indoaniline in (a); and (c) a double chloride of zinc and said indoaniline in (a). When the indoaniline is employed in combination with an aqueous alcoholic solution, a hair dyeing lotion which also sets the hair is provided by the inclusion therein of a cosmetic film forming resin.
