Composition for dyeing keratinic fibers comprises a polyguanidine derivative (I). Composition for dyeing keratinic fibers comprises a polyguanidine derivative of formula (I) or a salt thereof: [Image] X, R1-R3H, OH or 1-16C (un)saturated alkyl or hydroxyalkyl; Y : NHR; R : H, OH or 1-16C (un)saturated alkyl or hydroxyalkyl; A : 1-16C (un)saturated alkylene optionally substituted with OH, COOH, carboxylate or halo or interrupted by NH, O, S, COO, OCO, CONR, NRCO, NHCOO, OCONH, NHCONH or a benzene or 3-8C cycloalkane ring optionally substituted with 1-8C alkyl, OH or halo; one or more 6-7C aryl or 3-8C cycloalkane rings optionally substituted with 1-8C alkyl, OH or halo; or a 10-14C polyaryl or 6-10C polycycloalkyl chain optionally interrupted by 1-8C alkylene, NH, O, S, COO, OCO, CONR, NRCO, NHCOO, OCONH or NHCONH; n : 2-5000. An independent claim is also included for dyeing keratinic fibers by applying the composition to the fibers. |
