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.
该发明涉及式为##STR1##的4-杂环基-4'-乙烯基蒽的化合物。其中,Q是单环5-或6-成员芳香杂环环,未经取代或取代为非色团基团且不含融合苯环或1或2个融合苯环,或为双环9-成员芳香杂环环,苯基未经取代或取代为非色团基团,或为氰基,羧基,烷氧羰基或烷基磺酰基或芳基磺酰基,R.sub.o是氢,烷基未经取代或取代为非色团基团,R.sub.1是氢,烷基,烷氧羰基,氨基甲酰基或磺酰胺基,每个基团未经取代或取代为非色团基团,或为烯丙基,羧基,烷基磺酰基,芳基磺酰基或芳基烷基磺酰基,氰基,磺酸基或膦酸二烷基酯,R.sub.2是氢,烷基或烯丙基,每个基团未经取代或取代为非色团基团,但R.sub.1和R.sub.2中最多只有一个基团为氢。这些化合物用于漂白高分子量的有机物,特别是聚酯。它们可以与其他荧光增白剂混合使用。
