    Abstract: The present invention is directed to a hair dyeing composition comprising an azo dye of the following general formula (I) A - N = N - B 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.

    Abstract: The present invention is directed to a hair coloring method by using a composition comprising a specified ring-fused heterocycle direct dyestuff having the general formula (1) or a salt thereof wherein the formulas are as defined in the patent claims.Furthermore, the present invention is also directed to the composition. This composition has a surprisingly good hair coloring performance and compatibility with peroxides. The use of this composition leads to long lasting brilliant colors wherein the color is stable against washing of the hair and environmental influences.

    Abstract: PROBLEM TO BE SOLVED: To provide a hairdye composition capable of dyeing the hair in clear and deep color, resistant to sunlight, shampooing, sweat, friction and heat, stable to alkaline agent and oxidizing agent, having high dyeing power and resistant to fading with time and provide a dyeing method using the composition without decomposition of a dye.
    SOLUTION: The hairdye composition contains a direct dye expressed by general formula (1): DYE-(L)
    n -DIS and having a dissociative group. In the formula, DYE is a residue of a dissociative dye having a dissociative hydrogen atom in a chromophoric group and having an absorption peak at 400-700 nm in dissociated state; L is a bivalent bonding group; n is 0, 1 or 2; DIS is a dissociative group; and two L groups may be the same or different when n is 2.
