CHARGE-TRANSPORTING VARNISH

摘要

A charge-transporting varnish comprising a phenylamino-N,N'-diphenylquinonediimine derivative represented by the formula (1) as a charge-transporting substance. It becomes possible to provide a charge-transporting varnish comprising an oxidized oligoaniline, which has a high solubility in various organic solvents and also has a good filtration property because the varnish has no aggregation property. (1) wherein R<SUP>1</SUP> represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group; and R<SUP>2</SUP> to R<SUP>19</SUP> independently represent a hydrogen atom, a hydroxyl group, an amino group, a silanol group, a thiol group, a carboxyl group, a phosphoric acid group, a phosphate ester group, an ester group, a thioester group, an amide group, a nitro group, a substituted or unsubstituted monovalent hydrocarbon group, an organooxy group, an organoamino group, an organosilyl group, an organothio group, an acyl group, a sulfone group or a halogen atom.
