leuco bases: Colourless compounds formed by reduction of triphenylmethane dyes. Generally, they are amino or hydroxy derivatives of triphenylmethane. Use of this class name, which is more or less parochial to the technology of dyes, is not endorsed. E.g. (p-Me₂NC₆H₄)₂CHPh, the leuco base of Malachite Green. [The prefix "p-" in the chemical formula must be italicized.]  5, record 1, English, - leuco%20base
