| titleOfInvention | Alkanolammonium-containing triazinyl flavonate whiteners |
| abstract | A process for whitening paper in a size press includes contacting a cellulose sheet with a size press liquor that contains a surface size and a particular whitener containing sulfonate groups and cations, M, wherein at least 10% of all cations M have the formula n nin which R 5 to R 7 , independently of one another, denote hydrogen, a C 1 -C 4 -alkyl radical or an optionally further substituted C 2 -C 4 -hydroxyalkyl radical, and R 8 denotes an optionally further substituted C 2 -C 4 -hydroxyalkyl radical. The process provides superior paper whitening compared to a corresponding process in which the whitener cations are all sodium or potassium ions. |
