Beschreibung
Zusammenfassung:	The invention relates to the use of a surface size composition comprising at least one cellulose derivative selected from cellulose ethers, excluding carboxyalkyl celluloses, for providing compression strength for a fibrous web, such as paper, board or the like, preferably comprising recycled cellulosic fibres. The invention relates also to a method for surface sizing of paper, board or the like. L'invention concerne l'utilisation d'une composition de collage en surface comprenant au moins un dérivé cellulosique choisi parmi des éthers de cellulose, à l'exclusion des celluloses de carboxyalkyle, pour assurer une résistance à la compression d'une nappe fibreuse, telle que du papier, du carton ou similaire(s), comprenant de préférence des fibres cellulosiques recyclées. L'invention concerne également un procédé de collage en surface de papier, de carton ou similaire(s).
