A compound of the formula: Image I wherein A is II Image B is a group of the formula: Image III or Image IV when B is of Formula III, X is of Formula III; when B is of Formula IV, X is selected from H, phenyl, substituted phenyl, naphthyl, substituted naphthyl, thienyl, substituted thienyl, thiazol-5-yl and substituted thiazol-5-ylin which the substituents are selected from NR7R8, NO2, C1-4-alkyl, C1-4-alkoxy, C2-4-alkenyl, halogen, cyano and phenyl; each Q is independently selected from H, C1-4-alkyl, phenyl and benzyl; each R1 & R2 is independently H, C1-4-alkyl, trimethylene or C1-4-alkyl-substituted trimethylene which is also attached to the ortho carbon atom of the adjacent benzene ring; or R1 & R2 together with the nitrogen atom to which they are attached form an aliphatic heterocycle; each R3 & R4 is independently H, C1-4-alkyl, trimethylene or C1-4-alkyl-substituted trimethylene which is also attached to the ortho carbon atom of the adjacent benzene ring; or R3 & R4 together with the nitrogen atom to which they are attached form an aliphatic heterocycle; each R5 & R6 is independently H, C1-4-alkyl, trimethylene or C1-4-alkyl-substituted trimethylene which is also attached to the ortho carbon atom of the adjacent benzene ring; or R5 & R6 together with the nitrogen atom to which they are attached form an aliphatic heterocycle; each R7 & R8 is independently selected from H, aryl, C1-4-alkyl, substituted C1-4-alkyl, trimethylene and C1-4-alkyl- substituted trimethylene which is also attached to the ortho carbon atom of the adjacent benzene ring; or R7 & R8 together with the nitrogen atom to which they are attached form an aliphatic heterocycle; and wherein each benzene ring in Formulae II, III and IV has no further substituents or carries 1 or 2 further substituents selected from halogen, C1-4-alkyl and C1-4-alkoxy. The compound is suitable for use as a charge transport material in organic photoconductors, as a charge control agent in electroreprographic toners and as a colour former in pressure sensitive recording materials.
