Aqueous stable dispersions of UV-absorbent s-triazine compounds containing (a) 5 to 50 percent by weight of an n-triazine compound of the formula <IMAGE> (b) 0 to 18 percent by weight of an anionic compound, and (c) 0 to 18 percent by weight of a nonionic compound, with the proviso that at least one of components (b) and (c) must be present. These dispersions are excellent for improving the light fastness of dyeings on synthetic fibres, in particular polyester fibres or acid-modified polyester fibres. |
