Abstract
The present embodiments relate to a nail coating having a major advantage in that it enables a nail coating to adhere to a natural nail or uncoated nail for long wear periods without adhesion loss or other signs of breakdown of the coating. Nail topcoats with improved abrasion resistance are also disclosed. Adhesion of a composition for nail coatings be improved by addition of a polyhedral oligomeric silsesquioxane (POSS). Nail coating compositions that benefit from the addition of a POSS include enamels, reactive composition such as those containing acrylates, solventless compositions and water-based compositions.
