Abstract

The compounds of the formula I are prepared by reacting the correspondingly substituted benzaldehydes of the formula II with the correspondingly substituted benzimidazoles of the formula III. The condensation and the subsequent ring closure can be carried out with or without isolation of the intermediate stage. The substituents in the formula I are as defined in Claim 1. The new compounds of the formula I can be used as optical brighteners or as fluorescent dyes.
