Process for the preparation of an acidic triphenylmethane dye. The subject of this patent is a process for the preparation of an acidic triphenylmethane dye, which is characterized by "that 1-methyl-2-phenyl-3-p-chlorobenzoylindole is condensed with ethylbenzyl-m-toluidine, the substance thus obtained with a :
sulfonating agent and then heated with p-phenetidine, the chlorine atom being replaced by the remainder of the p-phenetidine
