1. Compound of formula (I) below, the addition salts thereof, the dimer thereof and also the organic or inorganic acid salts thereof, the optical isomers thereof, the geometric isomers thereof, and the solvates thereof such as hydrates: in which Ra, Rb and Rc denote, independently of one another, a hydrogen atom, or a linear or branched C1-C4 alkyl group, preferably a hydrogen atom or a methyl group; R denotes a linear or branched C4-C18 alkylene or alkenylene chain, preferably a linear C7-C18 alkylene chain; x denotes 0 or 1; when x is 0, the amine is tertiary, then Y denotes an anionic group, preferably Y is chosen from carboxylate, phosphonate, phosphate, sulfate and sulfonate groups; when x is 1, the amine is quaternary, Y denotes an anionic group, preferably Y is chosen from carboxylate, phosphonate, phosphate, sulfate and sulfonate groups; or a non-ionic group, preferably Y is chosen from carboxylic acid, phosphonic acid, phosphoric acid, sulfonic acid and sulfuric acid groups; it being understood that, when the compound of formula (I) contains an anionic or cationic filler, it is combined with one or more cationic or anionic counterions that afford formula (I) electrical neutrality. |
