Abstract

PROBLEM TO BE SOLVED: To obtain a hair dye composition stable even if containing no reducing agent, and capable of giving glossy dyed hair with intense color especially in a red-color range in a relatively short treatment time when used by mixing with a peroxide just prior to use. SOLUTION: This water-soluble hair dye composition comprises (A) at least one component selected from tetraaminopyrimidine, triaminohydroxypyrimidine and water-soluble salts thereof and (B) an oxidative dye containing at least one coupling agent selected from resorcinol, 2-methylresorcinol and 4- chlororesorcinol and contains no reducing agent.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye composition containing an oxidation dye as a main component and applied to hair after being mixed with a peroxide composition, and a hair dyeing method using the same.

[0002]

2. Description of the Related Art In a hair dye composition containing an oxidation dye precursor, in order to stabilize these components and prevent them from being oxidized before use, ascorbic acid,
A reducing agent such as alkali sulfite is added (for example,

ka ", 2nd edition (1989), p. 786). However, this method has the disadvantage that it is difficult to be compatible with other components in the composition. Also, the oxidation dye precursor composition usually consists of an aqueous solution, emulsion, dispersion or gel, and the hair dye mixture immediately before use to apply these usually offsets the antioxidant action of the reducing agent. Requires a substantial excess of peroxide. The hair dyeing effect is slowed down and also affects the quality of the dyeing obtained, especially its strength. Further, this hair dyeing method has a problem that a relatively long processing time is required.
