Abstract
Low dielectric constant curable compositions include a first alkyl (meth)acrylate monomer with 12 or more carbon atoms, a crosslinking monomer, a copolymeric additive of a polycarbosilane or a polycarbosiloxane, and at least one initiator. The curable composition is solvent free and inkjet printable. Upon curing the curable composition forms a non-crystalline, optically transparent layer with a dielectric constant of less than or equal to 3.0 at 1 MegaHertz.
