A pigment particle composition which comprises calcium carbonate particles and pigment particles, its method of manufacture and its use. According to the present invention, the calcium carbonate particles are carbonated so that they bind to each other, in which case calcium carbonate structures are generated, which comprise pigment particles and which form essentially opaque and stable pigment-calcium carbonate aggregates. It is possible to manufacture the composition by atomizing calcium hydroxide-bearing pigment slurry into a carbon dioxide-bearing gas, in which case the calcium hydroxide is carbonated in order to precipitate the calcium hydroxide particles to be attached to each other and the carbonation is continued until essentially all of the calcium hydroxide has been converted into calcium carbonate. The composition is suitable for use, among others, in paints, coating materials, fillers, polymers and printing inks.
