Reaction of a primary or secondary aminosilane with a cyclic carbonic acid produces hydroxylalkylene-carbamoylalkylene-alkoxysilane (referred to as “hydroxylcarbamoylsilane”), which can be used undiluted or in solution. A diurethane (meth) acrylate-silane precursor compound produced by reacting with a (meth) acrylate material having an isocyanate functionality, and optionally a catalyst such as a tin compound. Similarly, an article comprising a substrate, a base (co) polymer layer on the major surface of the substrate, an oxide layer on the base (co) polymer layer, and a protective (co) polymer layer on the oxide layer is described. The protective (co) polymer layer comprises the reaction product of at least one diurethane (meth) acrylate-silane precursor compound. The substrate may be a (co) polymer film or electronic device such as an organic light emitting device, an electrophoretic light emitting device, a liquid crystal display, a thin film transistor, or a combination thereof. A method of making diurethane (meth) acrylate-silane and composite film and its use in electronic devices are described. |
