Dyeing composition for keratin fiber

PURPOSE: To obtain a new oxidative dyeing composition capable of carrying out dyeing resistant to light rays, cleaning, bad weather and perspiration, comprising a specific hydroxybenzofuran and at least one of a p- and an o-type oxidative dye precursors. CONSTITUTION: This composition is obtained by combining one or more of hydroxybenzofurans of the formula (R1 and R2 are each H or an alkyl) (especially preferably 3-methyl-6-hydroxybenzofuran, 4-, 5-, 6- and 7 hydroxybenzofuran) as a coupler with a p- or an o- type oxidative dye precursor (e.g. p-phenylenediamine or 1-amino-2-hydroxybenzene) in an aqueous or an alcoholic aqueous medium and is used for drying keratin fiber, specific human hair. The weight ratio of the oxidative dye and the coupler in the total weight is 0.3-7wt.% and that of the compound is 0.05-3.5wt.%. A medium suitable for dyeing has preferably pH4-11.
