| titleOfInvention | Compositions of disulphonic fluorescent whitening agents |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to compositions for optic whitening of paper or cardboard. Composition includes at least two fluorescent whitening agents - derivatives of disulphonic bis-triazinylaminostilbenes, containing group -CO 2 M in aniline rings in para and/or ortho-position to aminogroup, where M is hydrogen, Li, Na, K, Ca, Mg, ammonium or ammonium, which is mono-, di-, tri- or tetra-substituted C 1 -C 4 -alkyl or C 2 -C 4 -hydroxyalkyl. Described is method of preparing said composition, its application, method of paper whitening and paper resulting from said process. n EFFECT: claimed composition possesses higher whitening ability in comparison with each of separate whitening agents and provides stable concentrated water compositions without addition of auxiliary solubility-improving substances. n 25 cl, 1 dwg, 1 tbl, 4 ex |
