摘要:
Pro-dyes of direct dyes having an enzymatically-labile functionality, e.g. glutaramide derivatives of direct dyes of formula (I) or their physiologically acceptable salts, are described, as well as compositions for dyeing keratinous fibers containing these pro-dyes, as well as compositions for dyeing keratinous fibers containing a combination of at least one pro-dyes and at least one enzyme capable of cleaving the glutaramide functionality in the pro-dye. A method for dyeing keratinous fibers with the aforementioned dyeing compositions is also described.
摘要:
The invention relates to means comprising 2-amino-5-ethylphenol or the physiologically-acceptable, water-soluble salts thereof for the colouring of keratin fibres, in particular human hair.
摘要:
The invention relates to an agent for coloring fibers, which is prepared before use by mixing an acidic component (A1), which contains at least one enamine of formula (I)/(Ia), with a component (A2), which contains a Schiff's base of formula (II) R7HC=NR8. The invention also relates to a method for temporarily coloring fibers according to which the coloring obtained by using said coloring agent is removed at any time by means of a decolorizing agent that contains sulfite.
摘要:
The invention relates to an agent for dyeing fibres, obtained by mixing two components. The invention is characterised in that the one component (component A2) comprises at least one carbonyl compound and the other component (component A1) comprises at least one indoline derivative of formula (I), or one 3H-indolium derivative of formula (Ia) and a multi-component kit for dyeing and subsequent decolourising of fibres, comprising both said agent, for dyeing the fibre and an agent for the reductive removal of the coloration.
摘要:
The invention relates to an agent for colouring fibres, said agent being obtained by mixing two components if necessary, by adding an alkalisation agent or an acid. Said agent is characterised in that one of the components (component A2) contains at least one electrophilic compound and the other component (component A1) contains at least one 1-benzopyrane of formula (Ia)/(Ib) or one 1-benzopyrylium-derivative of formula (I). The invention also relates to a method for the temporary colouration of keratin fibres, whereby hair is initially coloured with the above-mentioned known colouring agent and then discoloured by a reducing agent at any later given moment.
摘要:
The invention relates to compounds of Formula (V) and (VI), a method for the production thereof, and colouring agents containing compounds of Formula (V) and/or Formula (VI).

摘要:
The invention relates to an agent for dyeing keratin fibres. Said agent contains at least one compound having a nucleophilic reaction centre, at least one alcohol from the group consisting of aryl alcohol derivatives and benzyl alcohol derivatives, and at least one appropriate oxidation enzyme. The invention also relates to a method for dyeing keratin fibres using the inventive agent.
摘要:
The invention relates to a method for the production of 5-Aryl-1.3.3.-trimethyl-2-methylene-indoline-derivatives of formula (I) or salts thereof of formula (Ia). Said method is characterised in that 1 mole of a 5-Aryl-2.3.3-trimethyl-3H-indole-derivative of formula (VII) is reacted with 1 50 moles of a compound of formula R1-A at a temperature of between 20 - 180 °C, in an apolar aprotic or polar protic or polar aprotic solution, for between 1 and 44 hours. According to said method, the novel compounds of formula (I)/(Ia) and (V) can be obtained. The invention also relates to an agent for colouring keratin fibres containing at least one compound of formula (I)/(Ia) and at least one carbonyl/amine compound and a method for the temporary coloration of keratin fibres, whereby the keratin fibres are coloured with said agent and at a later time are de-coloured by a preparation containing sulphite.
