Patent

CA 2569882

The invention relates to hydrophobic salts of layered metal hydroxides, which can be obtained by adding one or more hydrophobic compounds from the group containing waxes and metallic soaps to a layered metal hydroxide salt in dispersion with intensive mixing, in a quantity of between 0.2 and 200 wt. % in relation to said metal hydroxide salt, the latter containing trivalent, bivalent and optionally monovalent metal cations and one or more organic anions A of formula (I) X-R-Y. In said formula: X represents hydrogen, hydroxy, carboxy, sulphato or sulpho; Y represents carboxy, sulphato or sulpho; and R represents an aliphatic, cycloaliphatic, heterocycloaliphatic, olefinic, cycloolefinic, heterocycloolefinic, aromatic, heteroaromatic, araliphatic or heteroaraliphatic group comprising between 2 and 50 C-atoms, whereby said group can contain one or more substituents from the group comprising hydroxy, amino, halogen, C1-C22 alkyl, C1-C22 alkoxy, C1-C22 alkene- (CO)-O-(CH2CH2O)0-50-alkyl, C1-C22 alkene-(CO)-O-(CH2CH2O)0-50-haloalkyl, carboxy, sulpho, nitro or cyano. The liquid medium is then optionally removed, dried and isolated to produce a powder. The inventive compounds are used as electrostatic charge control agents, in particular in the field of electrophotography.

L'invention concerne des sels hydrophobés d'hydroxydes métalliques en couches obtenus par addition d'un ou plusieurs composés hydrophobes du groupe des cires et savons métalliques, à un sel d'hydroxyde métallique contenant des cations métalliques trivalents, bivalents et éventuellements monovalents, et un ou plusieurs anions organiques A de la formule (I) dans laquelle X est hydrogène, hydroxy, carboxy, sulfato ou sulfo, Y est carboxy, sulfato ou sulfo et R est un radical aliphatique, cycloaliphatique, hétérocycloaliphatique, oléfinique, cyclooléfinique, hétérocyclooléfinique, aromatique, hétéroaromatique, araliphatique ou hétéroaraliphatique, portant 2 à 50 atomes de C, un ou plusieurs substituants des groupes hydroxy, amino, halogène, C¿1?-C¿22?-alkyl, C¿1?-C¿22?-alkoxy, C¿1?-C¿22?-alkylène-(CO)-O-(CH¿2?CH¿2?O)¿0-50?-alkyl, C¿1?-C¿22?-alkylène-(CO)-O-(CH¿2?CH¿2?O)¿0-50?-halogénoalkyle, carboxy, sulfo, nitro ou cyano pouvant être présents, en dispersion sous mélange intensif, dans une quantité de 0,2 à 200 % en poids par rapport au sel d'hydroxyde métallique, et éventuellement extraction, séchage et isolation du milieu liquide en tant que poudre. Les composés selon l'invention sont employés en tant qu'agents de commande de charge, notamment dans l'électrophotographie.
