Abstract
Official abstract text for this publication.
The present invention relates to a colorant for hair dyeing containing a compound represented by the following general formula (I), a composition for hair dyeing containing the same, and a hair dyeing method: (in the formula, R 1 , R 2 and R 3 each independently represent a hydrogen atom, a linear or branched alkyl group having from 1 to 6 carbon atoms, or a linear or branched alkoxy group having from 1 to 6 carbon atoms, and An − represents an inorganic anion or an organic anion).
First claim
Opening claim text (preview).
1 . A colorant for hair dyeing, comprising a compound represented by the following general formula (I): (in the formula, R 1 , R 2 and R 3 each independently represent a hydrogen atom, a linear or branched alkyl group having from 1 to 6 carbon atoms, or a linear or branched alkoxy group having from 1 to 6 carbon atoms, and An − represents an inorganic anion or an organic anion). 2 . The colorant for hair dyeing according to claim 1 , wherein in the general formula (I), the An − is an inorganic anion selected from the group consisting of a chloride ion, a bromide ion, an iodide ion, a sulfate ion, and a phosphate ion; or an organic anion selected from the group consisting of a monomethyisuifate ion, a monoethylsulfate ion, a benzenesulfonate ion, a p-toluenesulfonate ion, and a methanesulfonate ion. 3 . The colorant for hair dyeing according to claim 1 , wherein in the general formula (I), at least one of the R 1 , R 2 and R 3 is a linear or branched alkyl group having from 1 to 4 carbon atoms. 4 . The colorant for hair dyeing according to claim 1 , wherein in the general formula (I), the R 1 and R 2 are both methyl groups. 5 . The colorant for hair dyeing according to claim 1 , wherein in the general formula (I), the R 1 , R 2 and R 3 are all methyl groups, and the An − is a chloride ion. 6 . A composition for hair dyeing comprising: the colorant for hair dyeing described in claim 1 ; at least one auxiliary agent selected from the group consisting of a moisturizer, a swelling agent, a penetrant, a solvent, a pH regulator, a surfactant, a fragrance, and a thickener; and water. 7 . A hair dyeing method using the composition for hair dyeing described in claim 6 .
