    摘要： A hydrophobic filler material for alkaline paper is disclosed. The filler material comprises finely divided particles of an inorganic material, a majority of particles having a surface all of which is substantially modified with a water soluble C12-C22 fatty acid salt and a metal ion in an amount at least effective to complex all of the fatty acid salt present. An alkaline paper is disclosed. The alkaline paper comprises a hydrophobic filler material comprising finely divided inorganic material, a majority of particles having substantially all of their surface being modified with a water soluble C12-C22 fatty acid salt. A method for improving sizing of alkaline paper is disclosed, comprising preparing a filler material and adding the same to cellulose fiber. The filler material is prepared by selecting finely divided particles of an inorganic material and substantially modifying all of the surface of a majority of the particles with a C12-C22 fatty acid salt, forming a hydrophobic coating thereon.
