摘要： An azo dye represented by the following general formula (1) and a process for making the azo dye is disclosed. The process comprises a step in which a diazonium salt is formed by the reaction between an aminopyrazole represented by the general formula (3) and an diazotizing agent, a step in which a compound represented by the general formula (5) is formed by the reaction between the diazonium salt and an aromatic coupling agent represented by the general formula (4), and a step in which an azo dye represented by the general formula (6) is formed by the reaction between the compound represented by the general formula (5) and an arylating agent or a heterylating agent in the presence of a base.
