<p>The invention relates to a method of sizing paper and similar cellulose fiber based products containing precipitated calcium carbonate as a filler. A method of sizing paper and similar cellulose fiber based products containing precipitated calcium carbonate as a filler, characterised in that an aqueous suspension of pulp is dewatered and dried in the presence of an aqueous dispersion of a rosin-based sizing agent, which comprises a rosin component and from 5 to 75 percent by weight based on the rosin-based sizing agent of a rosin ester component, and an aqueous dispersion of a cellulose-reactive sizing agent, wherein the weight ratio of rosin-based sizing agent to cellulose-reactive sizing agent is from 1 : 1 to 20 : 1.</p> |
