Vinyl, however, costs half of what 100% acrylic resins cost, and polyvinyl acetate (PVA) is even cheaper, so paint companies make many different combinations of them to match the market.
Latex paints (emulsion paints British English, not to be confused with latex rubber) are an emulsion of polymer particles dispersed in water.
