The dye is composed of 60-80wt% compound(I-1), 8-15 wt% compound(I-2) and 12-25 wt% compound(I-3), made by coupling diazo compound obtained from diazofication of aromatic amine(II) compound of 2 mole, 1-amino-8-naphtol-3,6-disulfuric acid(III-1) of 1mole, 1,3-diaminobenzen-4-sulfuric acid of 1mole and 1-aminonaphtalene sulfuric acid of 2mole. The dye doesn't generate precipition in case of storing for long time at low temperature.
