<p>Photocurable liquid coating compositions adapted to provide primary coatings for optical glass fibers are disclosed. These compositions comprise a (meth)acrylate-terminated polyurethane, a (meth)acrylate of an unsubstituted or C1-C10 alkyl substituted phenol that is alkoxylated with a C2-C4 alkylene oxide and at least one alkylacrylate having a Tg below about -45 °C. Films produced from these ultraviolet light curable compositions are flexible and possess good water resistance and good wet adhesion.</p> |
