    摘要: The invention relates to an aqueous dispersion containing a cellulose-reactive sizing agent and an anionic hydrophobically modified cellulose-derivative, its preparation and use in the production of paper. The invention also relates to a substantially water-free composition containing a cellulose-reactive sizing agent and an anionic hydrophobicity modified cellulose-derivative, its preparation and use in the preparation of an aqueous dispersion cellulose-reactive sizing agent. The invention further relates to a process for sizing cellulosic fibers by addition of an aqueous sizing dispersion containing a cellulose-reactive sizing agent and a hydrophobically modified dispersing agent to a stock containing cellulosic fibers, and optional fillers, and dewatering the stock on a wire to obtain a web containing cellulosic fibers.
