摘要： The present invention is directed to a hair dyeing composition comprising at least one azo dye of the following general formula (1): A—N=N—B  (1) where A=monovalent, optionally substituted heterocyclic group binding via the carbon atom to the azo group, that does not contain carboxy (—CO2H) or sulfo groups (SO3H) or quaternary ammonium groups and B=heterocyclic, aromatic or alkyl group containing a dissociative proton and, which is free of carboxy (—CO2H) or sulfo groups (—SO3H) or quaternary ammonium groups. Additionally, the present invention describes a method of dyeing human or animal hair by using such a dye and the use of this direct azo dye for dyeing human or animal hair. The use of this direct azo dye can impart the hair with an extremely vivid colour and has a less colour fade over the time.

摘要： Provided is a hair dye composition containing a dissociative direct dye represented by the following formula (1): wherein, R1 to R4 each represents H or substituent, X represents OH or —NHSO2R5 (R5 representing an alkyl, aryl or heterocyclic group) and A represents a group of any one of formulas (Cp-1) through (Cp-12). The hair dye composition of the present invention is capable of strongly dyeing the hair with a vivid color tone without causing decomposition of the dye during the dyeing process, exhibits excellent resistance against sunlight, hair washing, perspiration, friction and heat, has a high stability against an alkali agent and an oxidizing agent, has a high dyeing property, and shows less color fade over time.

摘要： Provided is a hair dye composition containing a dissociative direct dye represented by the following formula (1): wherein, R1 to R4 each represents H or substituent, X represents OH or —NHSO2R5, R5 represents an alkyl, aryl or heterocyclic group, and A represents a divalent group capable of forming a methine dye as a whole compound, together with the portion other than A. The hair dye composition of the present invention is capable of strongly dyeing the hair with a vivid color tone without causing decomposition of the dye during the dyeing process, exhibits an excellent resistance against sunlight, hair washing, perspiration, friction and heat, has a high stability against an alkali agent and an oxidizing agent, has a high dyeing property, and has less color fade after the passage of time.
