Abstract
Abstract This invention relates to vinyl ether-based coatings for which properties such as color stability, thermal stability, mechanical stability, hydrolyric stability, and resistance to embrittlement may be maintained and properties hydrogen generation and blocking are minimized. The invention also relates to stabilizers which control these properties in the coatings. The coatings comprise a vinyl ether-containing composition polymerizable by actinic, gamma ray, or electron beam radiation comprising: (a) an oligomer or a mixture of oligomers which are monofunctional, multifunctional, or a mixture of both monofunctional and multifunctional and which have a reactive functionality chosen from the group consisting of epoxy, acrylate, vinyl ether, maleate, or mixtures thereof, (b) monomers which are monofunctional, multifunctional, or a mixture of both monofunctional and multifunctional monomers and which have a reactive functionality chosen from the group consisting of epoxy, acrylate, vinyl ether, maleate, or mixtures thereof, wherein at least one of (a) or (b) must contain a vinyl ether functionality; (c) a photoinitiator with an optional sensitizer, said photoinitiator which is chosen from the group consisting of a cationic photoinitiator and a radical photoinitiator; and (d) a thermal oxidation stabilizer. The composition also comprises additives comprising at least one additive chosen from the group consisting of: (e) a hydrogen stabilizer; (f) a light screen; (g) a color stabilizer; (h) a blocking stabilizer or slip agent; and (j) a coupling agent.
