Zusammenfassung:	The use in the manufacture of paper and novel additives comprising derivatives of starches having particular levels of water fluidity and which contain controlled proportions of cationogenic or cationic substituent groups as well as sulfo-succinate groups. The resulting paper containing the latter additives is characterized by improved retention of pigments and increased strength.
