Paper sized with 2-oxetanone sizing agent made from normal and branched fatty acids

摘要

A method of neutral or alkaline manufacturing a paper grade containing additives, particularly precipitated calcium carbonate as filler in which to the paper in its pulp slurry step is added 2-oxetanone based size which is made from a greater number than one of fatty acids having main chain comprising 6-22 carbons linked with each other by saturated bonds and said acid(s) including at least one with a branched carbon chain in order for control the hydrophobicity properties of the sheet and for securing the ink-jet printability of said paper grade.
