摘要： The conventional condensation of naphthalene-1,4,5,8-tetracarboxylic acid with 1,2-diaminobenzene gives the resulting naphthoylenebisbenzimidazole isomers together in the cis and trans form. It is desirable to shift the isomer ratio of the mixture obtained toward the desirable trans product and to reduce the amount of cis product obtained. It is also desirable to develop a process of preparation which optimizes the yield and improves the waste water situation.This object is achieved according to the invention by subjecting virtually stoichiometric amounts of the starting compounds to a precondensation at 60.degree. to 110.degree. C. in an aqueous medium and then completing the condensation in the aqueous medium in a second stage at 130.degree. to 180.degree. C.

摘要： The .alpha.-modification of cis-naphthoylenebis(benzimidazole) is unstable in many media and up to date has therefore only been used as a vat dye. However, according to the invention, the .alpha.-modification can readily be used for pigmenting in the mass polyolefins such as polyethylene, polypropylene or analogous copolymers. During pigmenting, the pigment which is prepared in a conventional manner, is stable in that modification and produces strong red dyeings.
