The invention relates to effect pigments comprising artificial platelet-shaped substrates which have at least one optically active coating, the effect pigments having a volume-average size-sum-through-distribution curve with the ratios D 10 , D 50 and D 90 , this size-sum-through-distribution curve having a span ΔD of 0.7 -1, 4 and the chip ΔD is calculated according to formula (I): ΔD = (D 90 -D 10 ) / D 50 , and wherein the mean thickness of the artificial platelet-shaped substrates is 500 nm to 2000 nm. |
