Abstract

The invention discloses a red disperse dye composition. The composition comprises a crude dye and an auxiliary, and is characterized in that the crude dye is composed of the following components in percentage by mass: 66 to 80% of a dye monomer A as shown in the structural formula of a formula (I) (shown in the description), 15 to 29% of a dye monomer B as shown in the structural general formula of a formula (II) (shown in the description), and 2 to 8% of a dye monomer C as shown in the structural general formula of a formula (III) (shown in the description). According to a brand-new red disperse dye combination scheme provided by the invention, compared with an existing red disperse dye, significant improvement in the aspects of dyeing property and the like of the red disperse dye composition is realized, better alkali resistance is realized, and good industrial application prospects are realized.

Description

[0001] Technical field: [0002] The invention relates to a red disperse dye, in particular to a red disperse dye composition. [0003] Background technique: [0004] At present, C.I. Disperse Red 167 is the main red dye in the market. Since the dyeing pH of C.I. Disperse Red 167 is 4~5, the problem of C.I. . [0005] In the Chinese invention patent with the patent number ZL2004100257869, a combination scheme of C.I. Disperse Red 145 and C.I. Disperse Red 50 is proposed, which can solve the problems of inconsistent color and light and color fastness. [0006] In the Chinese invention patent with the patent number ZL2005100503745, a combination plan of C.I. Disperse Red 145, C.I. Disperse Red 153 and C.I. good question. [0007] In the Chinese invention patent with the patent number ZL 2009100274246, a combination scheme of C.I. Disperse Red 145 and C.I. Disperse Red 153 is proposed, which can solve the problems of dyeing speed synchronization and alkali resistance of existin...
