1. A curable composition comprising:
20 to 40 weight percent of a functionalized phenylene ether oligomer having an intrinsic viscosity of 0.03 to 0.13 deciliter per gram, measured at 25° C. in chloroform using an Ubbelohde viscometer;
60 to 80 weight percent of a reactive diluent, wherein the reactive diluent is a (meth)acrylate-containing monomer; and
a photoinitiator;
wherein weight percent is based on the total weight of the phenylene ether oligomer and the reactive diluent; and
wherein the functionalized phenylene ether oligomer has the structure
