Beschreibung
Zusammenfassung:	The surface-treated calcium carbonate according to the present invention is composed of calcium carbonate surface-treated with a fatty acid-based surface treatment agent, the specific BET specific surface area (Sw), the heating reduction amount (As) per unit area, the brightness maintenance rate (%), the average pore diameter (Dxp) at which the mercury intrusion amount is the maximum in a specific pore distribution by a mercury intrusion method, and the average pore diameter amount [the maximum value of the mercury intrusion increase amount (Dyp)/the average pore diameter (Dxp)] are satisfied. 本发明的表面处理碳酸钙由用脂肪酸系表面处理剂进行了表面处理的碳酸钙构成，满足特定的BET比表面积(Sw)、每单位面积的加热减少量(As)、亮度的维持率(％)、在基于水银压入法的特定的细孔分布中水银压入量为最大的平均细孔直径(Dxp)、平均细孔直径量[水银压入增加量的最大值(Dyp)/平均细孔直径(Dxp)]。
