Abstract

Trichlorperylene tetracarboxylic acid diphenyldiimide is prepared by treating the di-imide with chlorine or chlorinating agents in an organic diluent which is not attacked by chlorine under the reaction conditions and in presence of a chlorine transferrer until the trichloro body is formed. Suitable diluents are nitrobenzene and trichlorbenzene and chlorine transferrer are iodine or sulphur. Two examples are given. The product dyes fast clear scarlet-red shades. Specification 26690/13, [Class 2 (iii)], is referred to.
