Abstract: In road marking paint based on acrylic resins, up to 50% and pref. 20-30% of the binder comprises polystyrene or a copolymer of styrene with up to 50% of a mono-olefinic comonomer, this (co)polymer having an average mol. wt. of >=20,000. Opt. pigmented polystyrene waste or foamed polystyrenes are pref. although copolymers with monomers such as acrylonitrile, butadiene, styrene etc. are also suitable. The paint dries more rapidly than corresp. systems not contg. polystyrene. The paint has good sub-and weathering-resistance and can be pigmented in the same way as systems without polystyrene.
