Description
en donde R1, R2, R3 y R4 tienen la definición que se ha descrito arriba, asimismo en todas sus realizaciones preferidas; y en donde
5 T equilibra la carga aniónica y representa el equivalente estequiométrico requerido de un catión seleccionado del grupo constituido por H+, catión de metal alcalino, amonio, mono-C1-C4-alquil-di-C2-C3-hidroxialquilamonio, di-C1-C4-alquil-mono-C2-C3-hidroxialquil-amonio, amonio que está mono-, di-o trisustituido con un radical C2-C3-hidroxialquilo y mixturas de los mismos.
Preferiblemente, la mixtura se realiza en solución acuosa.
10 Preferiblemente, T equilibra la carga aniónica y es un catión seleccionado del grupo constituido por H+, Na+, K+, amonio, N-metilN,N-di-etanolamonio, N,N-dimetil-N-etanolamonio, tri-etanolamonio, tri-isopropanolamonio y mixturas de los mismos.
Los compuestos de fórmula (21) y (22) son ejemplos específicos de los compuestos de fórmula (20), pero la inven15 ción no se limita a estos ejemplos específicos.

Se preparan soluciones de encolado por adición de un abrillantador óptico de fórmula (22) en tal cantidad que se
5 alcanza un intervalo de concentraciones finales de 2,0 a 10,0 g/l de abrillantador óptico, a una solución acuosa agitada de cloruro de magnesio (la concentración final es 8 g/l) y un almidón de patata aniónico oxidado (Perfectamyl A4692 de AVEBE B.A.) (concentración final 50 g/l) a 60ºC.
La solución de encolado se deja enfriar, se vierte luego entre los rodillos móviles de una prensa de encolado de laboratorio y se aplica a una hoja base de papel comercial AKD (dímero de alquil-cetena) de 75 g/m2, encolada y
10 blanqueada. El papel tratado se seca durante 5 minutos a 70ºC en un secador de lecho plano. El papel secado se deja acondicionar, y se mide luego respecto a blancura CIE en un espectrofotómetro calibrado Elrepho.
El ejemplo se repite tanto en ausencia de cloruro de magnesio, como con el cloruro de magnesio reemplazado por una cantidad equivalente de cloruro de calcio.
Los resultados se resumen en la Tabla 2, y demuestran claramente la ventaja de la utilización de cloruro de magne
15 sio para alcanzar niveles superiores de blancura en comparación con el caso en que el abrillantador óptico está presente únicamente como la sal de sodio.
