摘要： The invention relates to a method of sizing paper and similar cellulose products containing precipitated calcium carbonate as a filler. According to the method, 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 a rosin ester component, and an aqueous dispersion of a cellulose-reactive sizing agent. The invention also relates to an aqueous dispersion of sizing agents which comprises a rosin-based sizing agent, which contains a rosin component and a rosin ester component, and a cellulose-reactive sizing agent.
