Dyes, liquid, corrosive, n.o.s. or Dye intermediates, liquid, corrosive, n.o.s
A dye is a colored substance that is soluble in some solvent; by contrast pigments are insoluble or nearly so in all solvents. Because of their solubility, dyes can chemically bind to the material they color. Dye is generally applied in an aqueous solution and may require a mordant to improve the fastness of the dye on the fiber. The majority of natural dyes are derived from non-animal sources such as roots, berries, bark, leaves, wood, fungi and lichens Wikipedia
