摘要：
Brightener mixtures containing from 75% by weight to 100% by weight, based on the weight of the mixture, of the bisstyryl compounds of the formulae I and II ##STR1## in a weight ratio from 10:90 to 70:30, formulations containing the novel mixtures, and also their use for optically brightening synthetic, semisynthetic or natural polymer materials.
