Medium-low temperature environmental-friendly disperse dye composition

The invention discloses a medium-low temperature environmental-friendly disperse dye composition, which comprises the following components in percentage by weight: 3-94 percent of dye compound A as shown in the formula (1), 3-55 percent of dye compound B as shown in the formula (2), 3-60 percent of dye compound C as shown in the formula (3) and 0-2 percent of dye compound D as shown in the formula (4). The dye composition has the advantages of bright color shade, good synchronism during dyeing, good reproducibility, and good leveling-dyeing property, coverage property and each fastness, and particularly has more remarkable advantages on compatibility among dyes and sublimation fastness; and moreover, the invention is environmental-friendly and overcomes the defect that environmental protection and good fastness property cannot be achieved at the same time in the prior art.
