| 发明名称 | AZO compound and ink containing the compound | ||
| 摘要 | An object of the present invention is to provide an ink containing an azo compound which is excellent in solubility in a solvent and has a high extinction coefficient. The present invention relates to an ink comprising a solvent having a relative permittivity of 3 or less, as measured at a frequency of 1 kHz and at 22° C. and having a solubility in water of 20 mg/L or less at 25° C. and a specific azo compound. | ||

| 主权项 | 1. An ink comprising: a solvent having a relative permittivity of 3 or less, as measured at a frequency of 1 kHz and at 22° C., and having a solubility in water of 20 mg/L or less at 25° C.; and an azo compound, the azo compound being represented by formula (I):wherein R1, R2, D1, and A1 each independently represent an arbitrary substituent, A2 represents a substituent of formula (II): wherein D2 represents an arbitrary substituent, n represents an integer of 1 to 5, and when n is 2 or larger, two or more D2 groups present in one molecule may be the same or different, m represents an integer of 1 to 4, and when m is 2 or larger, two or more D1 groups present in one molecule may be the same or different, and X represents a nitrogen atom or an optionally substituted methine group. | ||
