A water-based emulsion paint, for example, is formulated with high refractive index opacifying pigment particles, dispersant, and polymer particles in which substantially all of the pigment particles (40) are disjuncted from one another and contained within an attached cluster of polymer particles (41) or have appendant polymer particles to give opacifying units having a nodular outline. Preferably micro-voids are trapped between particles and the dispersant is less than 1% of the pigment by weight.
