2. Description of the Related Art Conventionally, oxidative hair dyes using oxidative dyes such as paraphenylenediamine have been the mainstream, but these need to be applied under strong alkaline conditions, causing damage to hair or skin. There was a problem in safety, a problem of odor, or a problem in feeling of use such as a texture of hair after dyeing. For this reason, a hair dye using an acid dye that is less in these problems has been developed, and examples of such a hair dye are disclosed in JP-A-61-53211 and JP-A-62321.
-164612, JP-A-63-239209, JP-A-5-221840, JP-A-6-107.
529 publication etc. are mentioned.

However, unlike a hair dye using an oxidative dye, a hair dye using an acid dye does not cause destruction of a melanin pigment, so that there is a problem that fashionable dyeing and bright gray hair dyeing are difficult. To this end, JP-A 1-1759
In the 25 publication, by using an acid dye and an oxidizing agent at the same time, a hair dye that can be dyed widely not only for bright gray hair but also for fashionable hair is proposed. However, the acid dye and the oxidizing agent must be mixed immediately before use. The operation was complicated because it had to be performed. On the other hand, the hair dyeing properties of the hair dyes using these acid dyes are still extremely low, and as a solution to this problem, a method of improving the hair dyeing property by adjusting the viscosity of the composition to a low level to improve the penetrability is also considered. However, in this case, there is a drawback in that it drips during application to hair and stains the skin and clothes.

[0004]

The object of the present invention is that it can be dyed in a bright color of your choice, has shape retention properties when applied to hair, and that it can be prevented from sagging and soiling the skin or clothing. Alternatively, a hair treatment composition which has a reduced viscosity when left standing after application, allows the dye in the composition to easily penetrate into the hair, exhibits excellent hair dyeing properties evenly, and is easy to operate Is to provide.

[0005]

It was found that the hair dyeing property and stability are further improved by the addition, and that stable dyeing is obtained by blending a stable specific dye together with an oxidizing agent, and the present invention has been completed. It was

That is, the present invention relates to a dye, an amount of aromatic alcohol which is supersaturated at room temperature with respect to the nonvolatile aqueous part in the composition, an amount of a volatile solvent which dissolves the aromatic alcohol in the supersaturated part, and heat. Water-soluble polymer with gelling property,
