REACTIVE YELLOW DYESTUFF COMPOSITION EXPRESSING DEEP AND RICH YELLOW COLOR AND HAVING EXCELLENT STABILITY TO ALKALI COMPONENT

摘要

PURPOSE: Provided is reactive yellow dyestuff composition expressing deep and rich yellow color in fabric dyeing and having excellent stability to alkali component suitable for cold-pad dyeing and durability and homogeneous dyeing property, as well as build-up property. CONSTITUTION: The dyestuff composition comprises 40-90 wt.% of compound represented by formula(I) and 10-60 wt.% of compound represented by formula(II) (wherein R1, R2 are independently hydrogen, methyl, ethyl, methoxy, ethoxy, carboxyl, amino or hydroxyl group; R3 is hydrogen, methyl, ethyl, methoxy, ethoxy or sulfone group; R4, R5 are independently hydrogen, methyl, ethyl, methoxy, ethoxy, aceto, ureido or methylaceto group, and X is -CH2CH2SSO3H- or -CH2=CH2 and n is integer of 1-3.) The deep and rich yellow color means Dyeing power of the dye higher than molar absorptivity. Build-up means long term dyeing expression.
