Triazine derivatives and their use

摘要

The present invention relates to compounds having the formula: in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; R1 is hydrogen or hydroxy; R2 is C1-C4alkyl or phenyl; Y is -C(=O)-NR3R4 in which R3 and R4, independently, are hydrogen or C1-C4alkyl, -SO2- NR3R4 in which R3 and R4 have their previous significance, -C(=O)-R2 in which R2 has its previous significance or -C(=O)-OM in which M has its previous significance which are useful as ultraviolet absorbing agents(UVAs) and as fluorescent whitening agents (FWAs), and to a method of improving the sun protection factor (SPF) of textile fibre material, especially cotton, polyamide and wool, treated with the compounds.
