This invention discloses a class of quinalidine disperse yellow dyes with high sublimation fastness and their synthesis method, belonging to the field of disperse dye technology. This invention uses Disperse Yellow 54 as the parent core and introduces one of the following substituents at the 6-position of the quinalidine ring: ethyl, n-propyl, cyclopropyl, cyclobutyl, cyclopropylmethyl, methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, cyclopropoxy, cyclobutoxy, cyclopropylmethoxy, 2-methoxyethoxy, fluorine, chlorine, bromine, cyano, or nitro. This invention uses 6-substituted-2-methyl-3-hydroxyquinoline-4-carboxylic acid and phthalic anhydride as raw materials, and synthesizes the target dye in one step via a high-temperature condensation reaction. Experimental results show that the sublimation fastness of the dye of this invention reaches grade 4-5 or 5, significantly improved compared to Disperse Yellow 54 (grade 2-3), while maintaining excellent resistance to rubbing, perspiration, and sunlight. This invention has a simple synthesis process, high yield, and high purity, possessing extremely high industrial production value and market application prospects.

The invention relates to an ink set, and to a printing method using such an ink set, said ink set comprising at least a cyan ink, a magenta ink, a yellow ink and a black ink comprising disperse and / or solvent dyes in an aqueous vehicle, wherein said disperse and / or solvent dyes are selected from the group consisting of Disperse Yellow (64), Disperse Yellow (114), Solvent Orange (11), Solvent Violet 36, Solvent Violet (14), Solvent Red (169), Solvent Red (195), Disperse Blue 60, Disperse Blue (165), and mixtures thereof.

The invention relates to the technical field of textile printing and dyeing, and particularly discloses a disperse yellow-brown dye composition and application. The disperse yellow-brown dye composition comprises a component A and a component B. The component A is selected from a dye compound represented by a formula (I). The component B comprises one or more dye compounds represented by a general formula (II): formula (I); general formula (II); in the general formula (II), R1 is-CN; r < 2 > is-NR < 3 > R < 4 >; r < 3 > is-CH2C00CH3; and R < 4 > is-CH2C00CH3. When the disperse yellow-brown dye composition is used for dyeing the acetate-polyester blended fabric, the colors on acetate fibers and polyester fibers can have good homochromatism, and the disperse yellow-brown dye composition has relatively high fastness performance and a relatively good overall application effect.
