摘要:
The object of the present invention is a preparation for coloring fibers, which is prepared before use by mixing an acidic component (A1), containing at least one enamine of Formula (I)/(Ia) with a component (A2), containing a Schiff's base of Formula (II) as well as a method for temporarily coloring fibers, for which the coloration, obtained with the aforementioned coloring agent, can be removed once again at any time by a sulfite-containing decolorizing agent.
摘要:
The method of dyeing keratin fibers includes the steps of providing an oxidation dye precursor composition containing from 0.01 to 10 percent by weight of a total amount of at least one coupler compound and at least one developer compound, mixing the oxidation dye precursor composition with an oxidizing agent and applying the resulting mixture to the keratin fibers. The oxidation dye precursor composition is characterized by containing 1,4-diamino-2-methoxymethylbenzene, or a physiologically compatible salt thereof, either alone as sole developer compound, or in combination with other known developer compounds. The oxidation dye precursor composition can also contain at least one direct-dyeing dye compound and conventional cosmetic additive ingredients.
