Urea (multi)-(meth)acrylate (multi)-silane precursor compounds, synthesized by reaction of (meth)acrylated materials having isocyanate functionality with aminosilane compounds, either neat or in a solvent, and optionally with a catalyst, such as a tin compound, to accelerate the reaction. Also described are articles including a substrate, a base (co)polymer layer on a major surface of the substrate, an oxide layer on the base (co)polymer layer; and a protective (co)polymer layer on the oxide layer, the protective (co)polymer layer including the reaction product of at least one urea (multi)-(meth)acrylate (multi)-silane precursor compound synthesized by reaction of (meth)acrylated materials having isocyanate functionality with aminosilane compounds. The substrate may be a (co)polymer film or an electronic device such as an organic light emitting device, electrophoretic light emitting device, liquid crystal display, thin film transistor, or combination thereof. Methods of making the urea (multi)-(meth)acrylate (multi)-silanes and their use in composite films and electronic devices are described.
