The high strength that each component of the present invention can be deployed into by described proportional range, high fastness dyestuff and coloured light by ruddiness indigo plant to greenish blue.
Compound high-strength disperse dye of the present invention can be prepared as follows: after each dye monomer of metering ratio, auxiliary agent, water or other wetting agent are mixed, with shredder, carry out grinding distribution, then spraying is dried and makes described compound high-strength disperse dye.This is to well known to a person skilled in the art preparation method.In each described dye monomer, the former dyestuff of C.I. Disperse Blue-60, C.I. Disperse Blue-60 that dye monomer A, dye monomer B, dye monomer C, dye monomer D, dye monomer E can adopt respectively commercially available prod to produce as Zhejiang Bo Ao dyestuffs industries company limited: 3 former dyestuffs, the commercially available former dyestuff of C.I. EX-SF DISPERSE BLUE EX-SF 300 354, the former dyestuff of the former dye well C.I. of C.I. EX-SF DISPERSE BLUE EX-SF 300 165 DISPERSE YELLOW 184:1.
Compound high-strength disperse dye of the present invention also can be prepared as follows: by measuring than the finished product dyestuff C.I.
