FIELD: chemistry.SUBSTANCE: invention relates to quick-drying aqueous coating compositions used for road marking, as well as to road marking. The composition contains one or more anion-stabilised binding substances containing a polymer component with phosphoric acid functional groups. The polymer component has glass transition point (Tg) in the range of -30 to 60°C. The binder contains a polyfunctional amine component. The binding substance is contained in the composition in combination with one or more volatile bases. The volatile base is contained in an amount sufficient for stabilising the composition with at least partial deprotonation of the polyfunctional amine, and one or more phosphoric acid surfactants, such as alkyl ethoxylated phosphate. The invention also relates to double-component compositions containing said composition as one component and a second component containing an absorbent and/or a polyfunctional amine component.EFFECT: quick drying compositions exhibit stable viscosity and provide wear-resistance of quick-drying coatings even in moist application conditions.10 cl, 4 tbl, 7 ex |
