A method of producing a stable aqueous dispersion of a latex, solid particles and a dispersing agent, comprising contacting the latex with an anionic dispersing agent to form a modified latex, feeding the modified latex and the solid particles to a zone of high shear forces, and simultaneously subjecting essentially all of the modified latex and the solid particles fed to said zone to high shear forces to form a latex-particle slurry. By means of the invention, over 60 wt-% of the latex can be adsorbed on the solids. Latex immobilization increases the surface strength of final coating layer and allows for a decrease of latex consumption in paper and cardboard and paint applications.
