Man verwendet diese Weichmachungs-, Gelatinierungs- und Quellungsmittel für sich oder in Mischung miteinander oder auch in Mischung mit anderen bekannten Läsungs-und Weichmachungsmitteln erfindungsgemäß für die Herstellung von Lacken., Filmen u. a geformten Gebilden oder plastischen Massen aus Celltilos°zstern. wie @1;itrocellulose, For- mvlo°llulos°. Ac,-tvlcellulose Oder Cellulose- ätliern, wie ätlivl-, henzvlcalItilose.
