ABSTRACT:
The invention relates to a dispersible pigment concentrate, in particular for coloring of cement based building materials like concrete, and for coatings, paints and the like, that contains at least one pigment as well as, if necessary, bonding, dispersion and wetting agents, with a content of a disintegration agent, which, when contacting water (in sufficient amount), causes an essentially complete disintegration of the primary structure of the concentrate with subsequent release the pigment particle within one minute without any mechanical operation.
