Process for preparing precipitated calcium carbonate pigment, especially for use in inkjet printing paper coatings and precipitated calcium carbonate

摘要: The invention relates to novel and innovative PCC pigments, able be used in a paper coating formulations manufacture coated 'multipurpose' papers, particular for inkjet applications, whose print qualities would identical or quite similar high resolution commercial while maintaining reduced manufacturing production cost. Said pigments are obtained by carbonation process using flow rate of CO2/air, which leads porous agglomerates very specific structure unique properties, followed an upconcentration step leading substantially the same but with higher, appropriate, solids content.
