| titleOfInvention | Stable solutions of fluorescent brighteners |
| abstract | A stable weakly acid or neutral solution of quaternized fluorescent brighteners consisting essentially of a quaternized fluorescent brightener of the formula ##SPC1## n Wherein Y 1 represents hydrogen methyl, ethyl, methoxy, halogen or together with Y 2 represents a fused benzene ring, Y 2 represents hydrogen, methyl, ethyl, methoxy, halogen or together with Y 1 or Y 3 represents a fused benzene ring, Y 3 represents hydrogen, methyl, ethyl, alkoxy with 1 to 4 carbon atoms, halogen or together with Y 2 or Y 4 represents a fused benzene ring, Y 4 represents hydrogen, alkyl with 1 to 4 carbon atoms, methoxy, halogen or together with Y 3 represents a fused benzene ring, Y 5 represents hydrogen, alkyl with 1 to 4 carbon atoms or phenyl which is unsubstituted or substituted by methyl and/or methoxy, Y 6 represents hydrogen, alkyl with 1 to 4 carbon atoms, alkylsulphonyl with 1 to 4 carbon atoms, methoxy or halogen, Y 7 represents hydrogen, methyl, methoxy or halogen, Y 8 represents alkyl with 1 to 4 carbon atoms, hydroxyalkyl with 2 to 4 carbon atoms, cyanoethyl, phenyl, cyclohexyl or benzyl which is unsubstituted or substituted by chlorine, methyl or methoxy, Y 9 represents alkyl with 1 to 4 carbon atoms which is unsubstituted or substituted by hydroxy or alkoxy with 1 to 4 carbon atoms, benzyl which is unsubstituted or substituted by chlorine or methoxy or represents a radical --CH 2 CN, --CH 2 CONH 2 or --CH 2 COOR, wherein R represents an alkyl group with 1 to 4 carbon atoms, and Z represents halogen, an alkylsulphate with 1 to 4 carbon atoms or a phenylsulphonyl radical which is unsubstituted or substituted by methyl and, in the case of the weakly acid solution, a polar organic compound, water and a weak acid, and, in the case of the neutral solution, a polar, aprotic organic compound and water. |
