1. A blended composition of at least two distinct separate ingredients (1) and (2),
comprising
(1) coated and/or uncoated Al2O3 flakes having a particle thickness of 130-400 nm, D50-value of 15-30 μm, D90-value of 30-45 μm and a D10-value of <9.5 μm, wherein the coated Al2O3 flakes have one or more coatings on top of and completely encapsulating said Al2O3 flakes and forming one or more layers apart from the Al2O3 flakes, wherein said Al2O3 flakes are alpha-alumina flakes,
and
(2) one or more further distinct ingredients apart from said coated and/or uncoated Al2O3 flakes, which are one or more organic dyes, organic pigments, transparent pigments, opaque white pigments, colored pigments, black pigments, flake-form iron oxides, holographic pigments, liquid crystal polymers, or transparent, colored or black luster pigments based on metal oxide-coated mica or SiO2 flakes or fillers,
