Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a surface treated calcium carbonate capable of giving high viscosity and excellent thixotropy to a paste like resin composition such as polyvinyl chloride sol, acrylic sol, printing ink, a coating material, a polysulfide sealant, a silicone sealant or an epoxy based adhesive by being blended to the resin composition. SOLUTION: This surface treated colloidal calcium carbonate contains 0.5-10 wt.% zinc component expressed in terms of zinc metal to calcium carbonate, is surface-treated with a fatty acid, an alkali metal soap of the same or an ester compound of the same and has
