PROBLEM TO BE SOLVED: To provide a new arylamine polymer useful as a polymer material for an organic thin-film EL element having excellent light-emitting performance and excellent durability, a polymer material for an active layer of an organic transistor or an organic electronics such as a material for electrophotographic receptor.
SOLUTION: The dialdehyde compound is expressed by general formula (I) (R1, R2, R3and R4are each independently a halogen atom or a group selected from straight or branched-chain alkyl, alkoxyl and alkylthio groups; x, y, z and w are each independently an integer of 0-4; when the compound has two or more R1, R2, R3or R4groups, these groups may be the same or different; and B is a monocyclic, non-condensed polycyclic or polycyclic aromatic hydrocarbon group).
