Cationic nitrophenylenediamine derivatives of formula (I) are new: R1-R4 = H, Z, A, A'OH, 2-6C polyhydroxyalkyl, A'OA, aryl, benzyl, A'CN, A'CONH2, A'CONHA, A'CONA2, A'CSNH2, 1-6C trifluoroalkyl, A'SO3H, A'COOA, A'SOA, A'SO2NH2, A'SO2NHZ, A'SO2NHA, A'SO2NA2, A'COA, ANH2, ANHQ or ANQQ', or NR1R2 and/or NR3R4 is a 5- or 6-membered ring optionally containing other heteroatoms; A = 1-6C alkyl; A' = 1-6C alkylene; A = 1-6C alkyl optionally substituted by OH; Q, Q' = A, A'OH, 2-6C polyhydroxyalkyl, COA, CONH2, CONHA, CONA2, SO2A, CHO, 2-7C trifluoroalkanoyl, COOA, CSNH2 or Z; R5, R6 = H, halogen, Z, COA, COA'NH2, COA'NHZ, COA'NHA, COA'NA2, A'COA'NH2, A'COA'NHZ, A'COA'NHA, A'COA'NA2, COOH, COOA, SO2A, SO2NH2, SO2NHZ, SO2NHA, SO2NA2, A'SO2NH2, A'SO2NHZ, A'SO2NHA, A'SO2NA2, CONH2, CONHA, CONA2, A'CONH2, A'CONHA, A'CONA2, A, A'OH, 2-6C polyhydroxyalkyl, A'OA, 1-6C trifluoroalkyl, CN, ANH2, ANHQ, ANQQ', OR7 or SR7; R7 = H, A, A'OH, 2-6C polyhydroxyalkyl, Z, A'OA, aryl, benzyl, A'COOH, A'CN, A'CONH2, A'CONHA, A'CONA2, A'CSNH2, 1-6C trifluoroalkyl, A'SO3H, A'COOA, A'SOA, A'SO2NH2, A'SO2NHZ, A'SO2NHA, A'SO2NA2, A'COA, ANH2, ANHQ or ANQQ'; Z = cationic group. Independent claims are also included for the following: (1) a composition for dyeing keratinic materials, especially for direct dyeing of human keratinic fibers, containing one or more compounds (I); (2) a method for dyeing keratinic fibers, comprising applying the composition of (1) to the wet or dry fibers and drying the fibers without rinsing.
