Abstract
This invention concerns optically brightened polyester materials and, in particular, formed polyester articles such as fibers containing certain 2,5-bis(p-carboalkoxystyryl)oxadiazole compounds such as 2,5-bis(4'-carbomethoxystyryl)-1,3,4-oxadiazole. These compounds impart exceptional brightness to the polyester and themselves have good fastness and stability properties.
