      EXAMPLE: A compound of formula IV.
      USE: For dyeing organic fiber materials containing OH and carbonamide groups, and particularly suitable for dyeing cellulosic fiber materials.
      PREPARATION: For example, cyanuric chloride is reacted with diaminobenzenesulfonic acid, an aminobenzenesulfatoethylsulfone is added to the reaction mixture to carry out diazotation. Dimethylaminodihydroxypyrimidine is added thereto to couple with the resultant diazo compound.
