Abstract

The invention pertains to pigment granulates for the coloring of building materials and processes to manufacture such granulates. The pigment granulates are granulated from a mixture containing the pigment, at least one wetting agent and/or binder and/or explosive, an agent to reduce the tendency to blister and/or an agent to increase the pigment content in the mixture to be granulated.
