Abstract

The invention relates to a pigment having a high light scattering ability. It is characterized in that it comprises a core having a size exceeding 100 nm which is covered with a sealing layer of titanium dioxide (TiO2) and a film thereon of, for example, amorphous silicic acid. The invention also comprises a method for the production of a pigment having a high light scattering ability which includes stepwise covering of the core particles which are present in the form of a sole with titanium dioxide by hydrolysis of titanium compounds and finally covering by means of, for example, silicic acid from a de-ionized alkali silicate.
