Abstract
Photocurable liquid coating compositions adapted to provide primary coatings for optical glass fibers are disclosed. These compositions comprise an acrylate-terminated polyurethane, an acrylate of an unsubstituted or C.sub.1 -C.sub.10 alkyl substituted phenol that is alkoxylated with a C.sub.2 -C.sub.4 alkylene oxide and at least one alkylacrylate having a T.sub.g below about -45.degree. C. Films produced from these ultraviolet light curable compositions are flexible and possess good water resistance and good wet adhesion.
