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.

A moisture-curable composition, including at least one organic polymer P containing reactive silane groups, between 1.0 wt.-% and 25.0 wt.-%, preferably between 2.0 wt.-% and 20 wt.-%, in particular between 2.5 wt.-% and 10 wt.-%, based on the total composition, of dimethyl or diethyl esters of aliphatic C3 to C5 dicarboxylic acids, and at least one curing catalyst for alkoxysilane groups. The moisture-curable composition is particularly suitable as elastic adhesive, coating, filler, or sealant and shows superior overpaintability, in particular with automotive topcoats or similar paints.

The present invention relates to a cured product having excellent stain resistance and low gloss, a method of manufacturing the same, and an interior material including the cured product. The cured product according to the present invention includes, along with an acrylic oligomer, an oligomer having a functional group containing silicon (Si) and an oligomer having a functional group containing fluorine (F), and thus, has excellent stain resistance and can implement a micro-folded structure on a surface thereof through extreme ultraviolet rays to be used during curing, thereby being capable of realizing low gloss without a matting agent.
