ABSTRACT:
The invention relates to 4-heterocyclyl-4'-vinylstilbenes of the formula ##STR1## wherein Q is a monocyclic 5- or 6-membered aromatic heterocyclic ring which is unsubstituted or substituted by non-chromophoric groups and which contains no fused benzene rings or 1 or 2 fused benzene rings, or is a bicyclic 9-membered aromatic heterocyclic ring, phenyl which is unsubstituted or substituted by non-chromophoric groups, or is cyano, carboxyl, alkoxycarbonyl or alkylsulfonyl or arylsulfonyl, R.sub.o is hydrogen, alkyl which is unsubstituted or substituted by non-chromophoric groups, R.sub.1 is hydrogen, alkyl, alkoxycarbonyl, carbamoyl or sulfonamide, each of which is unsubstituted or substituted by non-chromophoric groups, or is alkenyl, carboxyl, alkylsulfonyl, arylsulfonyl or aralkylsulfonyl, cyano, sulfo or phosphonic acid dialkyl ester, and R.sub.2 is hydrogen, alkyl or alkenyl, each of which is unsubstituted or substituted by non-chromophoric groups, with the proviso that at most one of R.sub.1 and R.sub.2 is hydrogen. These compounds are used for whitening organic material of high molecular weight, especially polyester. They can be employed in admixture with other fluorescent whitening agents.
