Method of Applying Traffic Marking onto an Oily Road Surface and Traffic Paints Formulated Therefor

摘要

A process for improving the adhesion of traffic markings on a road surface comprising applying on said road surface a layer of a paint of aqueous traffic comprising a polymer having a molecular weight in the range of 1,000 to 200,000 and Tg of -10 ° C to 10 ° C, said polymer being polymerized from a monomer mixture containing from 10% to 99.9% by weight, based on the total weight of polymer solids, of solid hydrophobic monomers having an index eta Hansch at least 3.5 and selected from the group consisting of 2-ethylhexyl acrylate, butyl methacrylate, stearyl methacrylate, methacrylate cetiliscosilo, lauryl methacrylate and vinyl aromatic monomers, and wherein said hydrophobic monomers include from 0.1% to 50% by weight, based on the total polymer weight, of at least one of said vinyl aromatic monomers.
