Process for azo coupling reaction using diazonium salt and coupler having releasing group, and recording material containing the coupler |
摘要 |
A process for an azo coupling reaction is provided that has a large coupling reaction rate and an excellent coloring density and exerts high coupling activity using a stable coupler, and a recording material containing the coupler is provided. The process for an azo coupling reaction comprises carrying out a coupling reaction of a diazonium salt and a coupler to make the diazonium salt form color, and the coupler has certain specified structures.
