摘要:The present invention is on polymers derivatized with an organic deposition-enhancing group for their enhanced deposition onto keratin fibers, especially human hair. The deposition-enhancing group is a di-hydroxyl phenolic compound with a spacer alkyl group bound to a reactive amine or carboxyl group, which reacts with one of the hydroxyl, carboxyl, primary and secondary amine groups on the polymeric backbone. The invention is on the method of synthesizing such compounds and compositions comprising the compounds.

摘要:The object of the present invention are diketopyrrolopyrroles of the general formula (I)wherein, independently of one another, Q1 and Q2 represent an optionally substituted, aromatic, isocyclic or heterocyclic group with 5 to 14 atoms in the ring, the heterocyclic group containing at least one oxygen, nitrogen or sulfur atom, and the R1 and R2 groups, independently of one another represent hydrogen or a Y-B+A- group, with the proviso that at least one of the R1 and R2 groups is not hydrogen; B+ is an aromatic, aliphatic, alicyclic, aromatic heterocyclic or non-aromatic heterocyclic, quaternary ammonium group or a quaternary phosphonium group; Y is an optionally substituted linear or branched C1 to C6 alkylene group and A- is an anion; a method for their synthesis as well as agents, containing compounds of formula (I), for dyeing keratin fibers.
