Abstract
Abrasion resistant, radiation curable compositions are provided for forming coatings over plastic substrates. Such compositions are particularly provided for forming an abrasion resistant, tintable coating over polycarbonate ophthalmic lenses. Generally, the radiation-curable coating comprises 10 to 50 parts of polyacryloylated alkane polyols containing up to about 20 carbon atoms and an average of at least three O-acryloyl groups; and 20 to 80 parts of polyacryloylated alkoxylated polyols containing up to about 20 carbon atoms and an average of at least three O-[acryloyl-(polyalkylene oxide)] chains, wherein each of the polyalkylene oxide chains comprises from one to 20 alkylene oxide groups.
