    摘要: A waterborne paint for traffic marking contains as an emulsion binder, a support polymer formed of styrene and acrylic acid monomers and having an acid value of between about 50 and about 250 and a hydrophobic emulsion polymer comprised of acrylic ester monomers and optionally including styrene monomers. The support polymer, in aqueous ammonia solution, acts as a surfactant, maintaining the emulsion polymer within micelles. Paints in accordance with the invention contain between about 10 and about 15 wt. percent of the emulsion polymer, between about 60 and about 75 wt. percent fillers or pigments and between about 9 and about 18 wt. percent water. Due to the high solids loading and low water content, the waterborne traffic marking paint is fast drying. Colored paints prefereably utilize banded pigments.
