Abstract
The object of the invention is an agent for coloring fibers, which contains at least one aromatic aldehyde compound, at least one compound of formula (I) or (II) and an alkanolamine, in which R1 represents a C1 to C3 alkyl group, a C1 to C3 alkoxyalkyl group or a C1 to C3 hydroxyalkyl group and R2 represents hydrogen or a hydroxy group, a methoxy group, a halogen atom, an amino group or a dimethylamino group and A− represents an anion, such as chloride, bromide, sulfate, hydrogen sulfate, monomethyl sulfate, acetate, lactate or iodide; a method for coloring fibers using this agent, as well as a multicomponent kit for coloring and, later on, decolorizing fibers.
Claims16
An agent for coloring fibers, said agent containing an alkanolamine, at least one aromatic aldehyde compound and at least one quinolinium compound of formula (I) or (II),
- wherein R1 represents a C1 to C3 alkyl group, a C1 to C3 alkoxyalkyl group or a C1 to C3 hydroxyalkyl group and R2 represents hydrogen or a hydroxy group, a methoxy group, a halogen atom, an amino group or a dimethylamino group and A− represents an anion.
A method for coloring hair, said method comprising the steps of:
- a) providing an agent for coloring the hair, said agent comprising containing an alkanolamine, at least one aromatic aldehyde compound and at least one quinolinium compound of formula (I) or (II):
- wherein R1 represents a C1 to C3 alkyl group, a C1 to C3 alkoxyalkyl group or a C1 to C3 hydroxyalkyl group and R2 represents hydrogen or a hydroxy group, a methoxy group, a halogen atom, an amino group or a dimethylamino group and A− represents an anion;
- b) applying the agent to the hair and allowing the agent to act on the hair for a period of 5 to 60 minutes at a temperature of 20° to 50° C.;
- and
- c) rinsing the hair with water and subsequently drying the hair.
A multicomponent kit for coloring and later decolorizing fibers, wherein the kit contains a coloring agent and a decolorizing agent, said decolorizing agent having a pH of 4 to 8 and comprising at least one member selected from the group consisting of sulfites, hydrogen sulfites, thioglycolic acid and salts of thioglycolic acid;
- and
- wherein said coloring agent comprises an alkanolamine, at least one aromatic aldehyde compound and at least one quinolinium compound of formula (I) or (II):
- wherein R1 represents a C1 to C3 alkyl group, a C1 to C3 alkoxyalkyl group or a C1 to C3 hydroxyalkyl group and R2 represents hydrogen or a hydroxy group, a methoxy group, a halogen atom, an amino group or a dimethylamino group and A− represents an anion.
