Problems solved by technology

[0004] The aforementioned semi-permanent hair dye formulations have the disadvantage that the color imparted by them usually shows low durability
In addition, it is difficult to obtain purple, blue and gray shades because the number of dyes that can impart these shades is extremely limited

Embodiment A

[0174] The dyes listed in Table 1 below were dissolved in Basic Formulation 1 with the following compounds:

[0175] General formula (I) dyestuff 0.5g

[0176] Isopropanol 5.0g

[0177] Ammonium hydroxide (25%) 5.0g

[0178] water up to 100g

[0179] pH 10.2

example B

[0181] The dyes listed in Table 2 below were dissolved in Basic Formulation 2 with the following compounds:

[0182] General formula (I) dyestuff 0.5g

[0183] Isopropanol 5.0g

[0184] Ammonium hydroxide (25%) 5.0g

[0185] Hydrogen peroxide (50%) 6.0g

[0186] water up to 100g

[0187] pH 10.2

[0188] Dyeing efficiency

[0189] a) Approx. 1.5 g of alkaline formula 1 was applied to 1 g of undamaged white goat hair for 30 minutes at 30°C. At the end of the treatment time, the hair was rinsed with water, shampooed and then dried.

[0190] The color of the hair was recorded for each example (this will also apply to each of the examples below) by measuring the L, a and b values ​​of the hair before and after coloring using a hand-held Datacolor Mercury color measuring instrument, and according to Known equation: ΔE=(ΔL 2 +Δa 2 +Δb 2 ) 1 / 2 Calculate the value of ΔE, which is a known colorimetric measurement.

[0191] The results are shown in Table 1

Abstract

The present invention refers to dyestuffs of the general formula (I) wherein R, R 1 , X, Y, Z, T and A - are defined as given in claim 1, dyestuff mixtures and hair dye compositions comprising them, as well as a process for colouring hair.

Description

technical field [0001] The present invention relates to hair coloring compositions comprising anthraquinone hair coloring agents. Background technique [0002] Hair dyes can be classified according to the dyes they use, or according to whether they have a melanin bleaching effect. Typical examples include two-part permanent hair dyes consisting of a first part comprising an alkaline agent, an oxidation dye and optionally a direct dye such as a nitro dye, and a second part comprising an oxidizing agent ; and a one-part semi-permanent hair dye comprising an organic acidic or basic agent, and an acid, basic or direct dye (such as a nitro dye). [0003] However, the aforementioned permanent hair dyes have the disadvantage that the shades imparted by the oxidation dyes are not so vibrant and they damage the hair. Attempts have been made to apply nitro dyes or cationic dyes to two-component hair dyes containing oxidizing agents to produce various shades (see, for example, Japane...
