A charge transport varnish comprising a phenylamino-N, N'-diphenylquinone diimine derivative represented by formula (1) as a charge transport material. Thereby, since it shows high solubility with respect to various organic solvents and shows non-aggregation property, the charge-transporting varnish containing the oxidative oligoaniline with good filterability can be provided.n n n n n n n n (In formula, R < 1> represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, R < 2> -R < 19> mutually independently represents a hydrogen atom, a hydroxyl group, an amino group, a silanol group, a thiol group, a carboxyl group, a phosphoric acid group, and a phosphate ester Group, ester group, thioester group, amide group, nitro group, substituted or unsubstituted monovalent hydrocarbon group, organooxy group, organoamino group, organosilyl group, organothio group, acyl group, sulfone group, or halogen atom Indicates.) |
