Silicone/multifunctional acrylate barrier coatings

A composition comprising:

• the reaction product, optionally dissolved in a solvent, of an aminofunctional silane having at least one molecule of the formula
• wherein
• 0≦a≦4
• R1 is independently hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, acryl, methacryl, alkylaryl, R2—SiRm(OR)3-m, or an alkylene linking group having 2 to 12 carbon atoms connected to one or two nitrogen atoms, with the proviso that at least one R1 is a hydrogen atom and at least one R1 and R2—SiRm(OR)3-m group, where m is 0, 1 or 2, and R is independently a hydrogen or an alkyl group having from 1 to 6 carbon atoms;
• R2 is independently selected from the group consisting of:
• linear or branched alkylene groups having from 1 to 12 carbon atoms;
• arylene groups having from 6 to 12 carbon atoms;
• and linear or branched hydrocarbon groups having from 1 to 16 carbon atoms and at least one alcohol, alcohol ether, ester, amide, urea, thiourea or polyether group,
• a multifunctional acrylate having a molecular weight of from 100 to 3000;
• and an ethylenically unsaturated dicarboxylic acid or a monoalkylester thereof.
