Abstract

The invention discloses an azonaphthalene dicarboximide compound shown as a formula (I). In the formula (1), R1 is C1-C5 aliphatic hydrocarbon, aromatic hydrocarbon, substituted aromatic hydrocarbon or C3-C5 oxygen-containing aliphatic hydrocarbon; the substituted group of the substituted aromatic hydrocarbon is p-methoxy; R2, R3 and R4 are independently hydrogen, C1-C2 alkane, C1-C2 alcoxyl hydrocarbon, halogen or nitryl; the composition of the azonaphthalene dicarboximide compound consists of the following raw materials in part by mass: 20 to 60 parts of azonaphthalene dicarboximide compound, and 40 to 80 parts of auxiliary agent; and the auxiliary agent is an anionic surfactant. The azonaphthalene dicarboximide compound has the properties of excellent color fastness to sunlight, washing fastness and the like; and the composition has good dyeing property, color fixation and good lifting power.

Description

(1) Technical field [0001] The invention relates to a disperse dye, in particular to an azonaphthalimide compound and its composition, preparation and application. (2) Background technology [0002] With the rapid development of polyester fiber and the improvement of people's requirements for textiles, higher requirements are put forward for the dyeing performance and environmental protection performance of disperse dyes. The market needs disperse dyes with higher lifting power and better fastness properties in all aspects. The dyes currently available on the market such as C.I. Disperse Orange 30 and C.I. Disperse Red 167 have only Grade 4 fastness to washing and rubbing fastness, which will cause white or light-colored parts to be stained with other colors during the washing process, so it is urgent needs improvement. (3) Contents of the invention [0003] The object of the present invention is to provide a disperse dye compound and its composition with excellent washi...
