  • Process for producing two-tone coated substrates
    Patent number: 7943197
    Abstract: A process for producing two-tone coated substrates, comprising the successive steps: a) providing a non-color-imparting pre-coated substrate, b) applying a color-imparting coating of Color 1 at least to one or more regions of the substrate side facing an external observer, c) curing the coating of Color 1, d) masking the desired region of the coating of Color 1, e) applying a color-imparting coating of Color 2 to the unmasked regions of the substrate side facing the external observer without deliberately curing the coating of Color 2, f) unmasking the regions masked in step d), g) applying a clear coat to the whole of the substrate side facing the external observer and h) curing the clear coat.

  • Aqueous binders containing layered silicate, process for the production thereof and use thereof in aqueous coating compositions
    Publication number: 20060142459
    Abstract: Aqueous binders containing 0.2 to 7 wt-% of layered silicate, relative to binder solids content, obtainable by converting a homogeneous mixture of layered silicate and non-aqueous binder (precursor) into the aqueous phase by mixing with water and, in the case of a binder precursor, concluding synthesis of the binder in the aqueous phase.
