摘要：
The invention relates to novel heteroaromatic trinuclear direct dyes, to dye compositions containing these dyes and to the process for dyeing keratin fibres using them. In particular, the invention relates to heteroaromatic trinuclear direct dyes comprising a pyridine nucleus. These novel dyes make it possible to obtain black shades that show good fastness and good stability in the dye compositions.
