Abstract

The invention comprises dyes of the formula <FORM:1043999/C4-C5/1> wherein A is an aromatic radical which may be substituted; R1 and R2 are H, alkyl, aminoalkyl, hydroxyalkyl, methoxyalkyl, aralkyl, cycloalkyl, aryl, halogen substituted aryl, or heterocyclic radicals form a heterocyclic ring with the nitrogen, and n is 1 or 2. The compounds are prepared by reacting a 2-aryl-aminoquinazarine with chlorosulphonic acid or with H2SO4 or oleum and chlorinating agents to give an intermediate of the formula <FORM:1043999/C4-C5/2> which is then reacted with an amine of the formula HN(R1)R2. A may be a phenyl, diphenyl or naphthyl group substituted by, halogen, alkyl, trifluoromethyl, alkoxy, aryloxy, acyl, sulphonic acid, alkyl- or aryl-sulphonyl groups.
