Abstract
A yellow, hot melt adhesive traffic marking composition is described. The yellow, hot melt adhesive traffic marking composition contains 10-25 percent by weight of a hot melt adhesive binder, 5-10 percent by weight of a thermally stable 1,5- or 1,8-substituted anthraquinone colorant selected from a 1,5- or 1,8-substituted anthraquinone aromatic thioether and a 1,5- or 1,8-substituted anthraquinone aromatic thioether polyester, and 65-85 weight percent of a filler. The yellow, hot melt adhesive traffic marking composition of the invention may also contain other components used in traffic marking compositions, such as a reflectivity aid, a plasticizer, or an impact modifier. Other optional components are discussed below. The yellow, hot melt adhesive traffic marking compositions may be applied to any paved surface.
