BACKGROUND OF THE INVENTION
The present invention relates to a method for dyeing hair, and more particularly to a method for iron mordanting with a specific disazo dye.
[0002]
[Prior art]
Conventionally, acid dyes or oxidative dyes are mainly used in hair dyeing. Acid dyes are inferior in fastness, and oxidative dyes contain amines, causing skin problems and allergies.

[Problems to be solved by the invention]
It is an object of the present invention to provide a practical dyeing method for hair that is robust and has few allergic disorders by iron mordant dyeing.
[0008]
[Means for solving the problems]
In order to achieve the above object, the present invention has been achieved by treating hair with a composition having a pH of 2 to 4.5 containing a disazo dye represented by the general formula (1) in the form of a free acid, and then an aqueous solution of an iron salt. It is characterized by iron mordanting with a mordant liquid comprising
[0009]
[Chemical 2]
[In the above formula, ring A may be substituted with Cl, a nitro group or an alkyl group having 1 to 3 carbon atoms, and ring B may be substituted with Cl, F or an alkyl group having 1 to 3 carbon atoms. Good. ]
[0011]
In the present invention, if the pH of the dye-containing composition is less than 2, hair embrittlement may occur.
A more preferable range of the pH value of the dye liquor is 2.5 to 3.5.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The dye-containing composition of the present invention may be prepared in the form of a solution, an emulsion, or a gel containing ethanol and benzyl alcohol depending on the method of application to hair.
After dyeing is completed, soaping is performed using a soaping agent.
The iron mordanting method of the present invention can be suitably used for dyeing hair.
[0013]
【Example】
Hereinafter, the present invention will be described specifically by way of examples.
Each fastness test and measurement were performed by the following methods.
Fastness to sweat alkali: JIS L0848-1996 (measured in gray scale)
Light fastness: JIS L0848-1996 (measured in gray scale)
Carbon arc lamp 63 ° C 10 hours Example 1
[0014]
[Chemical 3]
For 1 g of gray hair, 10% o.d. of the dye having the structure (2) in the form of a free acid is obtained. w. f. Add 10 cc of ethanol and 5 cc of benzyl alcohol, adjust the dye bath to pH 3.5 with acetic acid, prepare the dye bath at a bath ratio of 50: 1, maintain at 20 ° C. for 30 minutes, take out, wash with water, and bath ratio 20: 1 ferrous sulfate 3% o.d. w. f. The dyed product is put into the aqueous solution and stirred. After maintaining for another 10 minutes, the article to be dyed is removed from the dye bath and lightly washed with soapy water. Thereafter, it was washed with water and the dyed product was dried. The dyed product thus obtained was dyed dark black, and had good sweat alkali fastness and light fastness. The results are shown in Table 1.
Example 2
[0016]
[Formula 4]
For 1 g of gray hair, 10% o.d. of the dye having the structure (3) in the form of a free acid is obtained. w. f. Add 10 cc of ethanol and 5 cc of benzyl alcohol, adjust the dyeing bath to pH 3.5 with acetic acid, prepare a dyeing bath at a bath ratio of 50: 1, maintain at 20 ° C. for 30 minutes, take out, wash with water, and bath ratio 20: 1 ferrous sulfate 3% o.d. w. f. The dyed product is put into the aqueous solution and stirred. After maintaining for another 10 minutes, the article to be dyed is removed from the dye bath and lightly washed with soapy water. Thereafter, it was washed with water and the dyed product was dried. The dyed product thus obtained was dyed brown and had good sweat alkali fastness and light fastness. The results are shown in Table 1.
[0018]
Comparative Example 1
Disazo type C.I. I. No. Using a commercial black hair manicure containing Acid Black 1 as a main component of the pigment, white hair is dyed by a designated dyeing method. After dyeing, wash gently with soapy water. Thereafter, it was washed with water and the dyed product was dried. The fastness results of the dyeings thus obtained are shown in Table 1.
[0019]
Comparative Example 2
Monoazo type C.I. I. No. Using a commercial brown hair manicure containing Acid Orange 7 as the main component of the pigment, the gray hair is dyed by the designated dyeing method. After dyeing, wash gently with soapy water. Thereafter, it was washed with water and the dyed product was dried. The fastness results of the dyeings thus obtained are shown in Table 1.
[0020]
[Table 1]
【The invention's effect】
According to the present invention, iron mordant dyeing that is excellent in wet fastness and light fastness of hair, etc., and without fear of transfer to clothes is possible, and is particularly useful for white hair dyeing.
