ABSTRACT:

The present invention relates to biphenyl-substituted triazine compounds, to processes for the preparation of these compounds, to organic material stabilized with the aid of these compounds against damage by sunlight, heat and oxygen, to the corresponding use of these compounds as stabilizers for organic material, and to their use as light stabilizers for textile fiber materials and as sunscreens for the human skin.
If it is desired to increase the light stability of an organic material, especially a coating, a light stabilizer is usually added. A class of light stabilizers which is very frequently employed comprises the UV absorbers, which protect the material by absorbing the harmful radiation via chromophores. An important group of UV absorbers is the triphenyltriazines, as are described inter alia in EP-A-434 608, EP-A-520 938, U.S. Pat. No. 4,619,956, EP-A-483 488, EP-A-500 496, EP-A-502 816 and EP-A-506 615. Some bis-resorcinyl derivatives from this group are mentioned, for example, in CH-A-480 090, CH-A-484 695, U.S. Pat. No. 3,249,608, U.S. Pat. No. 3,244,708, U.S. Pat. No. 3,843,371, U.S. Pat. No. 4,826,978, EP-A-434 608, EP-A-520 938, GB-A-2 273 498 and WO-A-94/18 278.
It has now been found that certain biphenyl-substituted triazine compounds have surprisingly high absorption in the range from 300 to 400 nm which is important for organic polymers.
