    • A method of coloring keratinous fibers comprising contacting the fiber with and effective amount of a primary intermediate general formula (I) or water-soluble salts thereof in which one of the two groups R1 and R2 is hydrogen and the other is hydrogen, chlorine or fluorine; one of the two groups R3 and R4 is hydrogen, a C1-4-alkoxy group, a C1-4-alkyl group, a C1-4-hydroxyalkyl group, preferably with a terminal hydroxy group or halogen and the other is one of the groups: —O—CH2—CH═CH2, —CH═CH—COOX in which X is hydrogen or a physiologically tolerable inorganic or organic cation and, in the case when the group concerned is R3, the group (a) and, in the case when the group concerned is R4, (b), in which —A— in each case is one of the groups —(CH2)x— in which x=1 to 4, —O—(CH2)y—O— in which y=1 to 4, —O—(CnH2n—z(OH)z)—O— in which n=1 to 10 and z=1 or, when n is greater than or equal to 3, z=2, —O—(C2H4—O)u— in which u=1 to 4 and —O—(C3H6—O)v— in which v is 1 to 4 and oxidizing the primary intermediate to color the fiber. Brilliant hues with a high degree of fastness are obtained with the usual coupling agents, particularly when dyeing hair.
    • 一种着色角质纤维的方法,包括使纤维与有效量的两性基团R 1和R 2之一为氢的有效量的初级中间体通式(I)或其水溶性盐接触,另一种 是氢,氯或氟; R 3和R 4中的一个基团是氢,C 1-4 - 烷氧基,C 1-4 - 烷基,C 1-4 - 羟烷基,优选具有末端羟基或卤素, 另一个是以下基团之一:-O-CH 2 -CH = CH 2,-CH = CH-COOX,其中X是氢或生理上可耐受的无机或有机阳离子,并且在所涉及的基团是R 3的情况下, ,(a)组,在所涉及的组是R 4的情况下,(b),其中-A-在每种情况下都是 - (CH 2)x - 之一,其中x = 1〜 4,-O-(CH2)yO-,其中y = 1至4,-O-(C n H 2n-z(OH)z)-O-,其中n = 1至10且z = 1,或当n大于 u = 1〜4,-O-(C 3 H 6 -O)v - ,其中v为1〜4,氧化初级中间体 使光纤着色。 使用通常的偶联剂,特别是染发时可获得具有高牢度度的辉光色调。

    • Oxidation colorants which contain at least one secondary intermediate and at least one derivative of 5,6-dihydroxyindoline corresponding to formula (I): ##STR1## in which--independently of one another--R.sup.1 is hydrogen, a C.sub.1-4 alkyl group or a C.sub.1-4 hydroxyalkyl group,R.sup.2 is hydrogen or a --COOH group which may even be present as a salt with a physiologically compatible cation,R.sup.3 is hydrogen or a C.sub.1-4 alkyl group,R.sup.4 is hydrogen, a C.sub.1-4 alkyl group or a group --CO--R.sup.6 where R.sup.6 is a C.sub.1-4 alkyl group andR.sup.5 is one of the groups mentioned for R.sup.4,or a physiologically compatible salt of these compounds with an organic or inorganic acid in an aqueous carrier and which are free from oxidation dye precursors of the primary intermediate type enable hair to be colored in particular in black tones with no tinges of red. In particular, completely or partly grey hair can be colored in tones which come very close to the color of the hair before greying.
