Abstract

1,65,795. Electrophotographic liquid toners SCM CORPORATION. Sept.6, 1963 [Sept. 24, 1962], No.35369/63. Heading G2H. A liquid toner composition for developing a negatively charged electrostatic latent image comprises:- (a) an insulating liquid carrier, (b) positively charged pigment particles, (c) a salt of a divalent or trivalent metal and an organic acid, particularly an aliphatic acid having 2-18 carbon atoms, which salt is soluble in the liquid carrier or is dissolved in a liquid miscible and compatible with the composition, and (d) an antioxidant. Suitable pigments are carbon, talc, and metallic and organic pigments; these may be admixed with asphaltum, alkyd, epoxy or hydrocarbon resins. Suitable antioxidants are 2,6-ditert-butyl-p-cresol, aminophenols, hydroquinones, alkylated phenols and phenylenediamines. The toner composition may also contain a dispersant, e.g. siloxanes and disiloxanes containing C4-10 alkyl and alkoxy radicals, and esters, of aliphatic alcohols and oxygen containing acids of boron, silicon, phosphorus and titanium.
