Disperse dye

Disperse dyes are polar molecules containing anthraquinone or azo groups.

[1][2] The history of disperse dye production is closely related to the synthesis of cellulose acetate fibres.

[3] Disperse dyes are non-ionic in nature and partially soluble in water.

The interaction of dye molecule and polymer takes place with Van der Waals and dipole forces.

[4] Disperse dyes have better diffusion at boiling to a higher temperature.
