Polycondensation and related dyes,et been generally accepted. The Colour Index Editorial Board is provisionally using the term Condense dyes, and has defined the class as ‘dyes which during or after application react covalently with themselves or other compounds (other than the substrate) to form molecules of much increased size’.
