    摘要： Aqueous dispersions of rosin and synthetic sizing agent wherein the particles in the dispersed phase contain a mixture of rosin and the synthetic sizing agent and wherein the dispersions contain a polyaluminum compound. The dispersions are prepared by homogenization of a homo­genous mixture of rosin material and the synthetic sizing agent and the polyaluminum compound can either be present at the production or be added to an aqueous dispersion of mixed particles. The dispersions are used as sizing agents at the production of paper, paper board, board and similar products.
