Zusammenfassung:	To provide an opacifying cluster which may be added to a coating composition to provide a coating composition with low gloss and a high level of opacity.SOLUTION: The opacifying cluster can include a polymeric latex binder coalescing cluster components into a generally homogeneous particle. The cluster components may include discrete polymeric particles each defining a closed void volume therein, a plurality of kinds of inorganic pigment particles, and a plurality of kinds of extender pigment particles. The clusters may also include a porosity of the polymeric latex binder thereof defining a binder void volume. Also provided is a paint product including such a pigment cluster.SELECTED DRAWING: None 【課題】低い光沢（ＳｏｗＧｌｏｓｓ）と高い不透明性を有する塗料組成物を得るために、塗料組成物に加えることができる不透明クラスターを提供する。【解決手段】不透明クラスターは、クラスター成分をほぼ均一な粒子に合体させるポリマーラテックスバインダーを含んでよい。クラスター成分は、閉鎖ボイド容積をそれぞれ画定する個別ポリマー粒子、複数種の無機顔料粒子、および複数種のエキステンダー顔料粒子を含んでよい。本発明のクラスターはさらに、バインダーボイド容積を画定するある多孔度のポリマーラテックスバインダーを含んでよい。さらに、このような顔料クラスターを含むペイント製品が提供される。【選択図】なし
