    Improved radiopaque coatings particularly suitable for polymer substrates are described. A modified ion plasma deposition (IPD) method is used to provide coatings with macroparticle dense surfaces that have excellent radiopacity. The coatings are particularly adapted to polymer surfaces because of high adherence and resistance to peeling and flaking.
