  • Patent number: 7288584
    Abstract: The present invention refers to a mixing scheme containing a plurality of pigmented base paint compositions having defined colors and optionally one or more non-pigmented base paint compositions comprising at least one rheology controlled base paint composition containing at least one pigment selected from the group consisting of inorganic pigments, di-keto-pyrrolo-pyrrole type pigments, organic liquid crystal type pigments and carbon black and having the following rheology profile (1) an initial viscosity V1 at 20° C. of 65 Pa s or greater when measured at a shear rate of 10?3 s?1, (2) a viscosity V2 at 20° C. when measured at a shear rate of 10?3 s?1 immediately after subjecting to a shear rate of at least 15 s?1 whereby the viscosity V2 is 700 Pa s or less and is less than or equal to 70% of V1; (3) 24 hours after subjected by shaking to a shear rate of at least 15s?1 a viscosity V3 at 20° C.

  • Patent number: 6013324
    Abstract: A sprayable aqueous coating composition for motor vehicles comprising an aqueous dispersion of addition polymer microparticles having a crosslinked core and a non-crosslinked stabilising mantle containing acid groups, characterised in that the crosslinked core comprises: i) a crosslinked inner core of an addition polymer and ii) a crosslinked outer core of addition polymer which is made from at least 10% by weight of monomers having a solubility in water of less than 0.1% by weight ratio of the inner core to the outer core being in the range 10:90 to 90:10.
