[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye composition which is excellent in dyeing property and fastness and has a good feeling after dyeing.

[0002]

Conventionally, as a hair dye composition for hair,
An oxidative hair dye that uses an oxidation-reduction reaction to dye hair, and an acid dye that uses an acid dye to dye hair in an acidic region are used, using an oxidation dye such as a p-phenylenediamine compound. is there. Among them, the acidic hair dye is prepared by blending an acidic dye, a hair dye promoter such as benzyl alcohol and N-methylpyrrolidone, and a thickener such as hydroxyethyl cellulose, and an acid such as citric acid, or, for example, The pH was adjusted to 1.5-4.5 with salts of those acids such as sodium citrate. However, since such an acidic hair dye has insufficient dyeing property and fastness, it has been proposed to use an acid dye in combination with a hair dye accelerator for the purpose of solving the problem.
Many publications have been made including the publication No. 1 and JP-A No. 62-164612.

[0003]

However, since such an acidic hair dye contains a large amount of a hair dye accelerating agent, there is a problem in that the hair dyed with hair becomes dull.
Therefore, the present invention provides a novel hair dye composition that improves the drawbacks of such conventional acidic hair dyes and that is excellent in dyeing property and fastness and further has a good feel after dyeing. It was intended.

Means for Solving the Problems As a result of intensive research for such purpose, the present inventors have found that by using a specific compounding ingredient in combination with a water-soluble acid dye,
It has been found that a hair dye composition having excellent dyeing properties and fastness and having a good feel after dyeing can be obtained, and has completed the present invention.

That is, the present invention comprises a water-soluble acid dye A,
One or more water-soluble polymers B selected from amphoteric polymers and cationized polymers having a cation-charged nitrogen content in the solid content of 0.5 to 6.0%, an iron compound C, and an organic solvent D. And a water E, which is a hair dye composition.
