Abstract: PCT No. PCT/EP90/02199 Sec. 371 Date Jun. 25, 1992 Sec. 102(e) Date Jun. 25, 1992 PCT Filed Dec. 17, 1990 PCT Pub. No. WO91/09835 PCT Pub. Date Jul. 11, 1991.The invention relates to biscationic acid amide and acid imide derivatives with an anion of formula (BR9R10R11R12)-, where R9 to R12 are aliphatic, iso- or heterocyclic aromatic residues or aralkyl residues, which may be substituted by C1-C4-alkyl residues, C1-C4-alkoxy residues, aryl residues or halogen atoms (e.g. fluorine atoms), and mixtures of these compounds and mixed crystals with mixed anions and/or cations. The invention also relates to a process for preparing them. The new compounds are excellent colorless charge controllers in toners and developers for electrophotographic recording and as charge-enhancers in powders and paints for surface coating, in particular in triboelectrically or electrokinetically sprayed powder paints.

Abstract: N,N'-dimethyl-perylene-3,4,9,10-tetracarboxylic acid diimide is obtained as a valuable pigment of a pure red shade, by reacting perylene-3,4,9,10-tetracarboxylic acid anhydride at low temperatures with a dilute aqueous solution of at least the four-fold molar amount of methylamine. The so-obtained bis-ammonium salt of the bis-N-methyl amide is then heated without isolation to effect ring closure while spiitting off two mols of water and two mols of methyl amine. The product can be used without any finish operation or cah be aftertreated to yield a pigment of an exceptionally high transparency or of a good hiding power.

Abstract: PROCESS FOR PREPARING COPPER PHTHALOCYANINE PIGMENTS OF THE .alpha.- MODIFICATION A process for preparing very pure copper phthalocyanine pigments of the .alpha.-modification, wherein substituted or unsubstituted copper phthalocyanines having different degrees of purity are converted into copper phthalocyanine salts capable of being isolated, with the aid of suitable acids which dissolve the impurities contained in the dyestuff, wherein these salts are separated from the acid, the copper phthalocyanines of the .alpha.-modification are set free in a pure form from the copper phthalocyanine salts by the action of water and wherein the isolated copper phthalocyanine is subject in an aqueous suspension to a mechanical fine division. This process yields copper phthalocyanines of the .alpha.-modification in a very pure form without causing problems with respect to the waste water.
