Abstract

1,231,856. Nigrosine derivatives. CANON K.K. 22 April, 1968 [22 April, 1967], No. 18976/68. Heading C4P. The invention comprises nigrosine compounds of the general formula RCON(R<SP>2</SP>)D wherein R is a saturated or unsaturated, substituted or unsubstituted aliphatic group having at least 4 carbon atoms; R<SP>2</SP> is H or an aliphatic, aromatic or heterocyclic group and D is a nigrosine radial. They are prepared by reacting nigrosine with an aliphatic acid halide, preferably the chloride, in a solvent, e.g. dioxane. RCO is preferably oleoyl, stearoyl, myristoyl or erucoyl. The compounds are used as chemically combined toners in the development of electrostatic charge images.
