    摘要: Novel benzofuranylbiphenyl compounds of the formula ##STR1## which are unsubstituted or polysubstituted by radicals R=hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, phenoxy and benzyloxy and in which M is hydrogen and/or one equivalent of a non-chromophoric cation and n is the number zero, 1 or 2 and m is the number zero or 1, subject to the condition that n and m are not both zero, and the preparation and use thereof as fluorescent brighteners, for example for textiles and paper. The novel benzofuranylbiphenyl compounds are distinguished by their very good stability associated with excellent whitening properties.
