Abstract

GRUPOS COORDINADORES COMPLEJOS SENSIBLES A LA DESCOMPOSICION, SE PUEDEN ESTABILIZAR PARA LO CUAL SE DERIVAN CON AYUDA DE ACIDOS CARBONICOS O SULFONICOS SECUNDARIOS O TERCIARIOS VOLUMINOSOS. ESTOS DERIVADOS ESTABILIZADOS SE PUEDEN AÑADIR A CAPAS DE ORIENTACION Y MEZCLAS DE CRISTALES LIQUIDOS, LO QUE CAUSA EN LAS PANTALLAS FLC UN AUMENTO DEL CONTRASTE Y DE LA LUMINOSIDAD.
