摘要：
The architectural compositions, such as paints and stains, include an additive comprising a plurality of latex particles added to an existing mixture of opacifying pigments and a film-forming binder as an admixture. Each latex particle is made from a latex polymer copolymerized with a polymerizable surfactant. The latex polymer is a non-film forming polymer at ambient temperatures.
