Pigment preparations, having a solid content of 10 to 60 wt-%, obtainable by mixing together, in the presence of at least one water-miscible organic solvent, pigments coated with a silicon-oxygen-matrix with at least one resin having carboxyl groups sufficient to provide an acid value of 10 to 100 mg KOH/g resin and having an number average molecular mass of 500 to 5000, wherein the ratio of pigment to resin is in the range of 1:0.3 to 1:10, can be used for the preparation of water-borne effect base coats with shear stability.
