ABSTRACT:
A surface treated calcium carbonate in which calcium carbonate is surface treated with a fatty acid surface treatment agent satisfying the following equation (a), and the surface treated calcium carbonate satisfying the following equation (b) is provided:in-line-formulae description="In-line Formulae" end="lead"?C12+C14 85(%) (a)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?andin-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?Pv 90(%), (b)in-line-formulae description="In-line Formulae" end="tail"?C12 is a ratio of a fatty acid surface treatment agent having an alkyl group of 12 carbon atoms, C14 is a ratio of a fatty acid surface treatment agent having an alkyl group of 14 carbon atoms, and Pv is a ratio of a volume (vol. %) precipitated in hexane.The surface treated calcium carbonate of the present invention can provide the resin compositions having slip resistance and slump resistance with a good balance between them, especially the resin compositions having an excellent slip resistance.
