摘要：
The invention relates to a composition for dyeing human keratin fibers, comprising, in a cosmetically acceptable medium, one or more cationic direct dyes comprising at least one carbon-carbon triple bond, for instance dyes of formula (I), (II) or (III) below: in which A1, A2 and A3, independently of each other, correspond to a cationic heterocyclic group and B1, B2 and B3, independently of each other, correspond to a particular aromatic nucleus; n may be equal to 1 or 2.
