Document Type and Number:

Japanese Patent JPS6054372

Kind Code:

A

Abstract:

Novel 4-heterocyclylvinyl-4'-styryl-biphenyls of the formula are described, i which A is an isoxazolyl, oxadiazolyl, pyrimidinyl or triazinyl radical which is unsubstituted or substituted by a non-chromophoric substituent, R1 is hydrogen or a non-chromophoric substituent and R2 is hydrogen, halogen, or alkyl; processes for the preparation of these compounds are also described. The novel 4-heterocyclylvinyl-4'-styryl-biphenyls can be used as fluorescent brighteners for high-molecular organic materials, in particular materials of polyamide and polyester, especially for polyester textiles.
