摘要： The invention is based on the idea of preparing porous calcium carbonate particles via a degradation reaction from a crystalline initial material which contains the initial components for forming calcium carbonate and additionally initial components for forming the reaction products to be removed from the initial material. In the reaction a substantial portion of the calcium carbonate forms a porous frame in the space occupied by the initial material, around the open space left by the matter leaving the initial material. The invention is also based on the use of such porous calcium carbonate particles as a pigment absorbing printing inks or their solvents on the surface of a printing substrate.
