ASYMMETRIC TRISAZO PIGMENT |
| 摘要 |
PROBLEM TO BE SOLVED: To obtain a new asymmetric trisazo pigment useful as a photoelectric conversion material having high sensitivity over a wide wavelength region from visible light to a near infrared light region. SOLUTION: This asymmetric trisazo pigment is represented by formula (1) (Ar<SP>1</SP>is a residue represented by formula (A); Ar<SP>2</SP>is a residue represented by formula (B); and R in formulae (A) and (B) is an alkyl.).
