Naphthol Dyes comprise phenols that offer solubility in alkaline solution and is substantive to cotton especially in presence of salt. These small molecules come with low to moderate substantivity but have properties of rapid diffusion into fibers. The higher substantivity also helps in achieving better rubbing fastness due to less AZO pigment formation on fiber surfaces.
As naphtholate ions are coplanar with elongated molecular structures, these work as colorless, low molecular weight direct dyes
When used in combination with bases, these provide for achieving large number of shades including red, maroon, brown, yellow, orange, blue, black
