  • Publication number: 20150159035
    Abstract: The present invention relates to dispersion-based paints or varnishes, more particularly for use as coating material (architectural paint), which have a low pigment volume concentration (PVC), lower than the critical pigment volume concentration (CPVC). The varnishes have high water vapour permeability and low water absorption. They are notable for good weathering resistance and resistance to wet abrasion, shade stability and chalking stability, and a variable, adjustable gloss.

  • Patent number: 5447981
    Abstract: A poly(meth) acrylic acid dispersion with an organic solvent as outer phase, the dispersed phase particles having a low polydispersity is obtained by the free radical polymerization of (meth) acrylic acid and optionally co-monomers, which bring about a cross-linking of the poly(meth) acrylic acid, in a nonpolar, organic solvent in the presence of stabilizers, costabilizers, and initiators. The stabilizer is a block copolymer.
