Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If vat dye rather than disperse
Vat dyes have different application methods and chemical structures, classified separately.
If reactive dye preparation
Reactive dyes for cellulose fibers use different fixation chemistry than disperse dyes.
If pre-dispersed in non-aqueous media for paint manufacturing
Pigments dispersed in nonaqueous media become artists' colors or paint pigments.
