Abstract
Compositions of water insoluble U.V. absorbers can be improved by the addition of a non-ionic surfactant which is an addition product of ethylene oxide or propylene oxide or both ethylene oxide and propylene oxide, and a mixture of fatty alcohols, fatty acids or fatty esters having 7-20 carbon atoms, preferably 14-18 carbon atoms or either tristyrylphenol or distyrylphenol. Such compositions have a good storage stability and excellent shear stability when the substrate to be dyed is a yarn which is in packed form.
