Abstract

Procedure for obtaining trisazo dyes, which, in the free acid form, correspond to the formula **(See formula)** where D means the remainder of a diazo component and K means the remainder of a coupling component of the formula wherein R is hydrogen or alkyl, R1 is hydrogen or alkyl, R2 is hydrogen, alkyl, or aryl, and X is amino or hydroxy, characterized in that an equivalent of a monoazo dye of the formula **(See formula)** where D has the meaning indicated above, it is coupled in an alkaline medium, on one side, with an equivalent of tetrazotized 4,4-diaminodiphenylamino-2-sulfonic acid, and then the intermediate product thus formed, which is not isolated, is it joins with a coupling component of formula KH, where K has the meaning indicated above.
