| description | The invention relates to cationic direct dyes of the formula I (1), wherein m and n are independently from each other 0 or 1, D is an aromatic or a cationic heteroaromatic group, which are further specified, K is an aromatic or heteroaromatic group, E1 and E2 are independently from each other =CH- or =N-, An is an anion and a is a number from 1 to 6 and R1 and R2 are independently from each other and further specified. The compounds show washfastness at hair-dying. |
