Title:
USE OF MALONALDEHYDE DERIVATIVES FOR DYEING FIBRES CONTAINING KERATIN
Document Type and Number:
WIPO Patent Application WO1999019558
Kind Code:
A3
Abstract:
The invention relates to the use of malonaldehyde derivatives of formula (I) for dyeing fibres containing keratin, in the presence of at least one compound with a primary or secondary amino group or hydroxy group chosen from primary or secondary aliphatic or aromatic amines, nitrogenous heterocyclic compounds, alpha - to omega -amino acids, oligopeptides made up of 2 to 9 amino acids and aromatic hydroxy compounds and/or at least one CH-active compound. R<1> and R<2> each represent a (C1-C4)-alkyl group independently of each other, and R<3> represents a hydrogen atom, a halogen atom, a (C1-C4)-alkyl group, a (C1-C4)-alkoxy group, a hydroxy-(C1-C4)-alkoxy group or an optionally substituted aryl or heteroaryl group, each pair of radicals being able to form a 5-, 6- or 7-ring.
