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.

Pavement marking composition

Polyfunctional ethylenically unsaturated polyureas, polythiocarbamateureas, and polyurethaneureas comprise (a) at least one segment derived from an aspartic ester polyamine; and (b) at least one polycarbonate, polyether, or polyester segment. The polyfunctional polymers are useful in preparing curable coatings, films, and articles.
