Beschreibung
Zusammenfassung:	The present invention relates to a method of manufacturing a paper grade containing precipitated calcium carbonate as filler. According to the invention, the ink-jet printability of said paper grade is advantageously improved by using a 2-oxetanone size which is made starting from non-branched and branched-chain fatty acids having main chain comprising 6-22 carbons linked with each other by saturated bonds. La présente invention concerne un procédé de fabrication d'une classe de papier renfermant comme charge du carbonate de calcium précipité. Selon cette invention, l'aptitude dudit papier à l'impression par jet d'encre est nettement améliorée par l'utilisation d'une colle de 2-oxétanone réalisée à partir d'acides gras à chaîne ramifiée et non ramifiée, dont la chaîne principale comprend 6 à 22 carbones liés les uns aux autres par des liaisons chimiques saturées.
