摘要：
Derivatives of para-phenylenediamine substituted with a pyrrolidinyl group of formula (I) and their addition salts where * n is between 0 and 4, it being understood that when n is greater than or equal to 2, then the radicals R1 may be identical or different * R1 represents a halogen atom an alicyclic hydrocarbon chain C1-C8, aliphatic or saturated or unsaturated, and may one or more carbon atoms be replaced by an oxygen atom, nitrogen, silicon or sulfur or by a group SO2 , or an onium radical Z, the radical R1 not carrying or peroxide radicals diazo bond, nitro or nitroso * R 2 represents an onium radical Z following selected from the radicals Z of formula (II), (III) or (IV) or -XC> -NR8-NR9R10 radical or - XP (O) (O-) OCH2CH2N + (CH3 ) 3, wherein X represents an oxygen atom or an -NR 11 radical, and R8, R9, R10 and R11 represent hydrogen, C1-C4 alkyl radical or a hydroxyalkyl radical C1-C4 * Formula (II) where * D is a covalent bond or an alkylene chain C1-C14 linear or branched, which may be interrupted by one or more heteroatoms selected from oxygen, sulfur or nitrogen and which may be substituted by one or more hydroxyl, C1-C8 alkoxy or amino, and which may bear one or more ketone functions * R4 R5 and R6, taken separately, they represent a C1-C15 alkyl radical monohydroxyalkyl radical C1-C6 a C2-C6 polyhydroxyalkyl radical an alkoxy radical (C1-C6) C1-C6 alkyl an aryl radical a benzyl radical an amidoalkyl radical C1-C6 a radical trialkyl (C1-C6) alkylsilane C1-C6 an aminoalkyl radical C1-C6 or an aminoalkyl radical C1-C6 whose amine is mono-, di- or trisubstituted by 25 alkyl C1-C4, alkyl (C1-C6) alkylcarbonyl, amido or (C1-C6) alkylsulfonyl, provided that, if D represents a covalent bond, then R 4 represents an aryl radical a benzyl radical an amidoalkyl radical C1-C6 radical trialkyl (C1-C6) alkylsilane C1-C6 an aminoalkyl radical C1-C6 or an aminoalkyl radical C1-C6 whose amine is mono-, di- or trisubstituted by an alkyl radical C1-C4, alkyl (C1-C6) alkyl
