The invention relates to pearlescent pigments comprising a largely transparent platelet-shaped synthetic substrate having a density ρS and at least one optically active coating having a density ρM, the substrate having an average size d50 from a range from 2.0 μm to 8.0 μm and an average height hS from a range from 40 nm to 110 nm and the total lead content of the pearlescent pigments is ≤10 ppm. The invention further relates to a method for producing the pearlescent pigments, and also to the use thereof.
