    • The invention relates to a method for dyeing keratin fibers, especially human hair. The inventive method comprises the following steps: optionally applying a pretreatment agent M1 to the fiber, using a dye M2 on the fiber which is optionally mixed immediately before application to the fiber from a component M2a, containing at least one oxidative dye pre-product of the developer type and/or an indole and/or indole derivative and a component M2b, containing an oxidative dye and/or an enzyme. If desired, a third agent M3 is added to the individual agents M2a or M2b before mixing them or to the mixture M2, and said dye M2 is rinsed from the fiber after a period of 5–10 minutes. At least one of the agents M1, M2a, M2b or M3 contains a compound from the vitamin B6 group. The invention further relates to hair pretreatment agents, to agents for dyeing keratin fibers, to their packing in corresponding kits and to the use thereof. The inventive compounds of the vitamin B6 group and their physiologically acceptable salts are useful as coupling components in the production of oxidative dyes that contain conventional developer and/or coupling compounds and/or indole and/or indole derivatives in a substrate appropriate for dyeing. The inventive compounds are further useful as active substances that improve the hair structure.
    • 本发明涉及一种染色角蛋白纤维,特别是人类头发的方法。 本发明的方法包括以下步骤:任选地将预处理剂M1施加到纤维上,使用纤维上的染料M2,其任选地在施用到来自组分M2a的纤维之前混合,所述组分含有至少一种氧化染料预产物 显影剂类型和/或吲哚和/或吲哚衍生物和包含氧化染料和/或酶的组分M2b。 如果需要,在混合它们之前或混合物M2中将第三试剂M3加入到各个试剂M2a或M2b中,并且在5-10分钟之后将所述染料M2从纤维上漂洗。 试剂M1,M2a,M2b或M3中的至少一种含有来自维生素B6组的化合物。 本发明还涉及毛发预处理剂,用于染色角蛋白纤维的试剂,其相应试剂盒中的包装及其用途。 维生素B6基团的本发明化合物及其生理上可接受的盐可用作在适于染色的底物中含​​有常规显影剂和/或偶联化合物和/或吲哚和/或吲哚衍生物的氧化染料的制备中的偶联组分。 本发明化合物还可用作改善头发结构的活性物质。

    • Agents for coloring keratin-containing fibers, in particular human hair, that contain encased oxidation dye precursor products. More-uniform coloring, which is independent of which strands are wetted first or last with the coloring product, is thereby ensured. The casing of the oxidation dye precursor products is made up of an encapsulating material made of methacrylic-acid, methacrylic acid-ester, or vinyl-acetate homo- or copolymers, or shellac, as well as at least one release agent. Contact time is equalized over time and shortened overall, resulting in a reduction in hair damage due to excessively long contact times. A method for manufacturing coloring agents for keratinic fibers, containing coated particles is also provided.
    • 用于着色含有包含氧化染料前体产物的含角蛋白的纤维,特别是人类头发的剂。 从而确保了更均匀的着色,其独立于首先或最后被着色产物润湿的丝束。 氧化染料前体产物的外壳由由甲基丙烯酸,甲基丙烯酸酯或乙酸乙烯酯均聚物或共聚物或虫胶制成的包封材料以及至少一种脱模剂制成。 随着时间的推移,接触时间相等并缩短整体,导致由于接触时间过长导致的头发损伤减少。 还提供了一种制造含有包被颗粒的角质纤维着色剂的方法。
