Abstract
A pavement marking composition comprises (a) a polyfunctional ethylenically unsaturated polymer selected from the group consisting of polyfunctional ethylenically unsaturated polyurethanes, polyureas, polythiocarbamates, polythiocarbamateurethanes, polythiocarbamateureas, and polyurethaneureas comprising at least one chain extender-derived segment and at least one polycarbonate, polyether, or polyester segment; and (b) at least one ethylenically unsaturated monomer. The composition can be easily applied, cures in a reasonable amount of time at any of a wide range of commonly-encountered temperatures, and provides pavement markings that exhibit both improved cold impact resistance and improved wear resistance.
