The principal advantages of anthraquinone dyes are brightness and good fastness properties, including lightfastness, but they are both expensive and tinctorially weak. However, they are still used to some extent, particularly for red and blue shades, because other dyes cannot provide the combination of properties offered by anthraquinone dyes, albeit at a price. Metallization would deteriorate the brightness and fastness properties, and there is no need to improve the lightfast­ness. Consequently, metallized anthraquinone dyes are of very little importance.
