Abstract
A water-dilutable UV light absorber composition and method for improving the lightfastness of dyed textiles is provided. The composition includes from about 5-75% by weight of an ultraviolet light absorbing agent selected from the group consisting of benzotriazole, benzophenone, and phenol substituted triazine; and from about 25-95% by weight of an organic solvent suitable for dissolving the ultraviolet light absorbing agent. The ultraviolet light absorbing agent is applied to the textiles in a concentration sufficient to result in an add-on in the range of between 0.4-4.0% by weight of the textiles when dry.
