Use of red iron oxide pigments in aqueous preparations

The invention relates to the use of a hematite pigment, the sum of the a*- values thereof in the Purton and in the lightening in the paint testing amounting to between 58.0 and 61.0 CIELAB units, preferably between 58.0 and 60.0 CIELAB units, more preferably between 58.5 and 61.0 CIELAB units, even...
