Abstract
A pearlescent pigment comprising micaceous particles having an adherent layer of rutile titanium dioxide thereon is prepared by effecting the deposition of hydrous titanium dioxide on the micaceous particles in the presence of iron and calcium, magnesium and/or zinc ions without the use of tin.
