Abstract

Naphthalene-dibenzimidazole vat dyes are prepared by reacting 1,4,5,8-naphthalenetetracarboxylic acid with a mixture of o-phenylenediamine and 4-ethoxy-o-phenylenediamine. The reaction may be effected in an inert solvent, e.g. in pyridine or acetic acid under reflux at 130-180 DEG C. or in water under pressure at 150-155 DEG C. Examples are given.
