    摘要: The present invention relates to novel s-triazine compounds, processes for their preparation and the use of these novel compounds as UV filters in sunscreen compositions. The novel compounds are those of the formula The triazine compounds of the formula (1) according to the invention are distinguished by a high UV absorption and are particularly suitable as UV filters, i.e. for protecting ultra-violet-sensitive organic materials, in particular the skin and the hair of man and animals, from the harmful action of UV radiation.
