DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an excellent effect of vividly coloring hair at the time of hair dyeing, has no discoloration or dye transfer, and has a richness such as suppleness and good finger passing of hair after dyeing. The present invention relates to an excellent hair dye composition giving a good texture.

[0002]

2. Description of the Related Art Conventionally, hair dyes containing acid dyes and natural dyes have been widely used in the home, barber and beauty industries because they have less damage to hair than other hair dyes. However, when the acid hair dye is applied to the hair and then washed with shampoo, the washing liquid has such a dark color that the washing liquid is unpleasant, and towels, clothes, or pillows when drying the towel after shampooing are finished. The major drawbacks are that the dye solution adheres to bedding such as covers and sheets, and the hair is exposed to sweat or rain and wets the hair, causing dye transfer to clothing and the like. In addition, there is also a disadvantage that a vivid color tone cannot be obtained particularly with black hair.

[0003] As a hair dye composition for improving such drawbacks and improving dyeing properties and color fastness, a specific acid dye is used and glycolic acid and / or pyrrolidone carboxylic acid and / or A hair dye composition using a combination of an alkali metal salt, an alkaline earth metal salt and an amine salt has also been proposed (JP-A-6-298630). However, they are not yet satisfactory in terms of dye transfer.

[0004] Further, as a hair dye composition for making gray hair inconspicuous by using it many times in a usage method such as a hair rinse, an organic solvent, a polyhydric alcohol, an acid dye,
A hair dye composition containing an acid has been proposed (Japanese Unexamined Patent Publication No.
-221840). However, this hair dye composition is also inferior in ease of use, for example, it is necessary to use it many times in order to obtain a sufficient hair dyeing effect, and is still satisfactory in terms of hair dyeing effect and transferability. It is not possible.

[0005]
