Formula of multi-component mixed disperse yellow dye

The invention relates to a disperse dye formula and especially relates to a formula of a multi-component mixed disperse yellow dye. The multi-component mixed disperse yellow dye is prepared by mixing 58 to 68wt% of a dyeing monomer A and 32 to 42wt% of a mixture of a dyeing monomer B and a dyeing monomer C, wherein the dyeing monomers A, B and C have the chemical formulas shown in the patent specification. The multi-component mixed disperse yellow dye can replace disperse yellow RGFL, and has dyeing effects the same as dyeing effects of the disperse yellow RGFL. A certain ratio of the mixture of the dyeing monomer B and the dyeing monomer C to the dyeing monomer A in the multi-component mixed disperse yellow dye can be kept. In finished dye preparation, assistants and water are added into the dyeing monomers, and the mixture is grinded by a sand mill and then is dried to form the finished product. The finished product has a disperse yellow RGFL color, can be used directly and can replace the disperse yellow R
