REACTIVE BLACK DYE COMPOSITION, WHICH HAS NO METAMERISM PHENOMENON IN DYING A CELLULOSE OR CELLULOSE/NYLON FIBER TO BLACK

摘要

PURPOSE: A reactive black dye composition is provided, which dose not shows a metamerism phenomenon in dying a cellulose or cellulose/nylon fiber to black and hardly stains other fibers. CONSTITUTION: The reactive black dye composition comprises 50-90wt% of a compound represented by the formula(I), 5-45wt% of a compound represented by the formula(II), and 5-45wt% of a compound represented by the formula(III). In the formula (I), R1 and R2 are hydrogen, a methyl group, an ethyl group, a methoxy group, an ethoxy group, or a hydroxyl group. In the formula(II), R1 is hydrogen, a methyl group, an ethyl group, a methoxy group, an ethoxy group, a carboxyl group, an amino group, or a hydroxyl group, R2 and R3 are hydrogen, a methyl group, an ethyl group, a methoxy group, an ethoxy group, or a hydroxyl group, R4 and R5 are hydrogen, a methyl group, an ethyl group, an acet group or a methylacet group, X is -CH2CH2OSO3H, -CH2CH2SSO3H, or -CH2=CH2, and n is an integer of 0-3. In the formula(III), R1 and R2 are hydrogen, a methyl group, an ethyl group, a methoxy group, an ethoxy group, or a hydroxyl group, X is -CH2CH2OSO3H, -CH2CH2SSO3H, or -CH2=CH2, and n is an integer of 0-3.
