| Zusammenfassung: | 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.
Opisuje sa neutrálny alebo alkalický spôsob výroby druhu papiera s obsahom aditív, najmä zrážaného uhličitanu vápenatého ako plniva, pri ktorom sa vofáze kašovitej vlákniny na reguláciu hydrofóbnosti hárka a zaistenie potlačiteľnosti uvedeného druhu papiera pri atramentovej tlači pridáva hydrofobizačný glej na báze 2-oxetanónu pripraveného z jednej alebo viac mastných kyselín, ktoré majú nasýtený hlavný reťazec obsahujúci 6 až 22 atómov uhlíka,pričom najmenej jedna z uvedených kyselín má rozvetvený uhlíkatý reťazec. |
