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. 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 inorganic pigment particles, and a plurality 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.
