Abstract

Triarylmethanedyestuffs having in p-position to the carbinol carbon a replaceable substituent are reacted with aromatic primary amines which contain in o or p-position to the primary amino group a substituted amino group other than a monoacylamino group. In an example, a dyestuff having the formula <FORM:0449090/IV/1> is reacted with N-phenyl-o-phenylenediamine in the presence of pyridine. The following aromatic primary amines are also mentioned: 2 - aminodiphenylamine - 4<1> - sulphonic acid, asym : diethyl(amino) - p - phenylenediamine, asym : dimethyl(amino - p - phenylenediamine and N-benzyl-o-phenylenediamine.
