A number of benzothiazolylazo dyes, containing one or two substituents in the benzo ring of the benzothiazole, have been prepared. Their absorption spectra and fastness properties are compared with those of analogous phenylazo dyes. The bathochromic shift of the absorption maxima, the increase in absorptivities, and the better fastness properties of the benzothiazolylazo dyes are reported.
