Description

A class of synthetic dyes containing a basic functional group, such as an amide. The first basic dye was mauve, discovered in 1856 in England by William Perkin. Basic dyes will attach directly to an acidic site, such as those found in wool, silk, leather, acrylics, and polyesters. These dyes can be used on cotton and paper after the cellulose is mordanted with a tannin. Basic dyes produce bright colors with poor colorfastness; this can be improved by the use of tannin mordants. Despite their poor stability, basic dyes are still used for coloring construction paper and some silks because of their bright, clear hues.
