(57) [Summary] [PROBLEMS] To obtain a soft and natural finish with extremely low secondary adhesion while having high coloring power, and to have no residual color and good stability after shampooing. Provide color hair cosmetics. An amphoteric polymer resin represented by the formula (1), an acid dye, and a pigment are contained, and the compounding amount of the amphoteric polymer resin is 0.01% by weight or more and 1% by weight based on the total amount of the hair cosmetic. Less than, The compounding amount of the acid dye is 1 part by weight or more and less than 0.1 part by weight with respect to 1 part by weight of the amphoteric polymer resin, and the compounding amount of the pigment is 0.1 part by weight with respect to 1 part by weight of the total of the amphoteric polymer resin and the acid dye. It is characterized by being at least 0005 parts by weight and less than 1 part by weight. Embedded image (Wherein, R 1 and R 6 represent a hydrogen atom or a methyl group, R 3 and R 4 represent an alkyl group having 1 to 4 carbon atoms, and R 2 and R 5 represent 1 Represents an alkylene group having from 4 to 4 carbon atoms. Although R 7 represents an alkyl group having 1 to 24 carbon atoms, the 15% to 100% is stearyl group. Further, the cationization density of the amphoteric polymer resin is 0.3 to 0.8, And the average molecular weight is from 80,000 to 220,000. ) |
