Abstract
A process is described by which plastics dispersions of high water and saponification resistance are obtained which, due to their small average particle size diameter of 0.01 to 0.06 microns are especially useful as primers for porous substrates. In their penetration characteristics, the present dispersions can be compared with conventional solvent-based primers at comparable solids content. The dispersions are obtained in a one-step polymerization process.
