Abstract:
1. A ready-to-use composition for dyeing fibers, comprising: (i) at least one cationic direct dye chosen from compounds of formulae (I), (II), (III), (III′) and (IV) below, and (ii) at least one thickening polymer; (a) wherein said compounds of formula (I) are chosen from compounds of formula: in which: D is chosen from a nitrogen atom and a —CH group, R R X A is chosen from structures A in which: R R wherein when D represents —CH, when A represents A (b) wherein said compounds of formula (II) are chosen from compounds of formula: in which: R R R X B is chosen from structures B in which: R R (c) wherein said compounds of formulae (III) and (III′) are chosen from compounds of formulae: in which: R R R R D m=0 or 1, wherein when R X E is chosen from structures E in which R′ is chosen from C wherein when m=0 and when D in which R′ is chosen from C (d) wherein said compounds of formula (IV) are chosen from compounds of formula: in which: G is chosen from structures G in which: R R R together form, in G together form, in G R Z is chosen from an oxygen atom, a sulphur atom and —NR M is chosen from a —CH radical, —C(C K is chosen from a —CH radical, —C(C P is chosen from a —CH radical, —C(C wherein r denotes zero or 1; wherein R R X wherein if R wherein if K or P or M is C wherein if K is —N wherein if M denotes —N if P is —N if Z is a sulphur atom with R if Z is —NR J is chosen from: (1) radicals chosen from structure J in which: R R R R R (2) 5- and 6-membered nitrogenous heterocyclic groups optionally containing other heteroatoms and/or carbonyl groups and optionally substituted with at least one radical chosen from C wherein said at least one thickening polymer is chosen from polymers comprising: (ii) at least one unit comprising a fatty chain; (ii) (iii)
