Abstract: Composition comprises substituted iridoid compounds (I) and/or substituted furanol compounds (II), or their plant extracts, and at least one nucleophilic compounds (a)-(h) optionally comprising an anion or its mixture to ensure electrical neutrality of the composition, and polyallylimidazolium oligomers or polymers. Composition comprises substituted iridoid compounds of formula (I) and/or substituted furanol compounds of formula (II) and their optical and geometrical isomers, inorganic or organic acid salts or solvates, or their plant extracts, and at least one nucleophilic compounds of formula (a)-(h) or its optical or geometrical isomer, organic or mineral acid salt or solvate, where the nucleophilic compounds optionally comprise an anion or its mixture to ensure electrical neutrality of the composition, and polyallylimidazolium oligomers or polymers.

Provided that: when A is N, n is 0, X is CH and R8 is NH 2, then R9 is not H or CH 3; if Y2 is CR27, then q is preferably other than 0; and at least one of the radicals R31 is other than hydrogen and/or at least u is 1. Independent claims are included for: (1) coloring human keratin fibers, preferably hair comprising applying the composition on the fibers; and (2) a multicompartment device comprising a first compartment containing (I) or their plant extracts, and a second compartment containing (a)-(h), nucleophilic oligomers or polymers.
