Abstract
The invention relates to a stratified material with a coating which is deposited on one side or both sides and which is comprised of a planar substrate containing acrylate. The synthetic resin is modified by means of high-temperature resistant, polymerizable nanoparticles having a glass transition temperature of the homopolymerizates ≧150 ° C. Said nanoparticles comprise a core consisting of silicon dioxide and of at least one side chain which is covalently bound to the core via one or several oxygen atoms of the oxide, and which is of the formula (MeO) (Me—(CH ) —(OCO) —CR ═CH ) , wherein Me represents Si or Al, x is 1 to 3, m is 0 and 1, n is 0 to 6, y is 1 to 3 and R represents H or CH , whereby the free valences of Me represent a binding to another oxygen atom of the core or are saturated by alkoxy radicals.
