4,4'-DI(TRIAZOLYLAMINO)STILBENE-2,2'-DISULPHONIC ACID DERIVATIVES PRODUCED FOR INCREASING THE SUN PROTECTION FACTOR OF TEXTILES

摘要

The present invention provides new stilbene compounds which are useful as fluorescent whitening agents (FWAs), imparting high whiteness levels to textile fibre material treated with them, and which also impart a high sun protection factor (SPF) to textile fibre material treated with them. The present invention also concerns a method of imparting a high whiteness level and a high sun protection factor to textile fibre material, especially cotton, polyamide and wool, comprising treating the textile material with the new compounds.
