ABSTRACT:
Layered double hydroxide salts as charge control agents in electrophotographic toners and developers, in powder coating materials, electret materials and in electrostatic separation processes of chargeable materials, such as polymers, wherein the double hydroxide salt contains monovalent and/or divalent, and also trivalent, metal cations, and also contains one or more organic anions A of the formula (I)in-line-formulae description="In-line Formulae" end="lead"?X—R—Y (1)in-line-formulae description="In-line Formulae" end="tail"?whereinX is hydroxyl, carboxyl, sulfato or sulfo;Y is carboxyl, sulfato or sulfo, andR is an aliphatic, cycloaliphatic, heterocycloaliphatic, olefinic, cycloolefinic. heterocycloolefinic, aromatic, heteroaromatic, araliphatic or heteroaraliphatic radical having a total of at least 8 carbon atoms which can be substituted by one or several substituents from the group hydroxyl, amino, halogen, C1-C22-alkyl, C1-C22-alkoxy, —C1-C22-alkylene-(CO)—O—(CH2CH2O)0-50-alkyl,—C1-C22-alkylene-(CO)—O—(CH2H2O)0-50-haloalkyl, carboxy, sulfo, nitro or cyano.
