Alpha-Alumina flakes having a particle thickness of 130-400 nm, a D-value of 15-30 μm, a D-value of 30-45 μm and a D-value of <9.5 μm. Use of the alumina flakes in varnishes, paints, automotive coatings printing inks, masterbatches, plastics and cosmetic formulations. Also, use of the alumina flakes as a substrate for effect pigments and in organic dyes.
