Title:
特にインクジェット印刷紙コーティングで使用するための沈殿炭酸カルシウム顔料
Document Type and Number:
Japanese Patent JP2008538538
Kind Code:
A
Abstract:
The invention relates to novel and innovative PCC pigments, able to be used in a paper coating formulations to manufacture coated "multipurpose" papers, in particular for inkjet applications, whose print qualities would be identical or quite similar to high resolution commercial papers, while maintaining a reduced paper manufacturing and production cost. Said pigments are obtained by a carbonation process using a reduced flow rate of CO 2 /air, which leads to porous agglomerates of PCC of a very specific structure and unique properties, followed by an upconcentration step leading to substantially the same agglomerates but with a higher, appropriate, solids content.
