[0002]

2. Description of the Related Art As a hair dye, a two-part oxidative hair dye consisting of a first agent containing an oxidation dye intermediate and a second agent containing an oxidant has been widely used. This hair coloring agent is a dye that causes a colorless low-molecular weight oxidation dye intermediate to penetrate into the hair and undergoes oxidative polymerization in the hair to generate and dye a dye. These oxidative hair dyes can dye hair in various colors as desired.

[0003]

However, when the above-mentioned oxidative hair dye is used, discoloration is observed due to shampoo, sunlight, sweating, etc. There was a disadvantage of dyeing.

Means for Solving the Problems The present inventor has conducted intensive studies in view of the above-mentioned circumstances and found that 2- (β-hydroxyethyl) -p-phenylenediamine or a salt thereof, and p-phenylenediamine or a salt thereof. By blending in a specific ratio, natural dyeing was obtained, and an oxidized hair dye composition having good fastness to shampoo, light and sweat was obtained, and the present invention was accomplished.

That is, the present invention comprises the following components (a) and (b): (a) 2- (β-hydroxyethyl) -p-phenylenediamine or a salt thereof (b) p-phenylenediamine or a salt thereof And the weight ratio of (a) and (b) is (a) :( b) =
The present invention provides an oxidative hair dye composition characterized in that the ratio is 1: 0.01 to 3. Hereinafter, the present invention will be described in more detail.

[0006]

DETAILED DESCRIPTION OF THE INVENTION In the present invention, the component (a) used is 2- (β-hydroxyethyl) -p
-Phenylenediamine or a salt thereof. The compounding amount of the component (a) is 0.01 to 15% by weight, and 0.01% by weight.
If it is less than 15%, sufficient hair dyeing effect cannot be obtained and 15% by weight
Beyond that, the effect remains unchanged and economical. Furthermore, 0.1 to 10% by weight is preferable, and more excellent hair dyeing effect can be obtained by adding 0.1% by weight or more.
On the other hand, when it exceeds 10% by weight, the increase in the hair dyeing effect is small.

[0007] The component (b) used is p-phenylenediamine and its salts. The amount of the component (b) is 0.01 to 15% by weight. If the amount is less than 0.01% by weight, a sufficient hair dyeing effect cannot be obtained. Not a target. Moreover,
0.1 to 10% by weight is preferable, and by blending 0.1% by weight or more, a more excellent hair dyeing effect can be obtained. On the other hand, when it exceeds 10% by weight, the increase in the hair dyeing effect is small.

In the present invention, the weight ratio of the component (a) to the component (b) is determined as follows: (a) :( b) = 1: 0.01 to 3
By doing so, natural dyeing and excellent fastness can be obtained. Preferably (a) :( b) = 1: 0.01 to
0.5.

Further, as component (c), o-aminophenol, m-aminophenol, p-aminophenol, m-phenylenediamine, 2-chloro-p-phenylenediamine, picramic acid, α-naphthol, 5-amino -O-cresol, 2,4-diaminophenoxyethanol, 5- (β-hydroxyethylamino) -2-
