Abstract:
1. A radiation-curable, free-radically crosslinkable formulation, comprising, in reacted form: A) at least one radiation-curable free-radically crosslinkable component comprising at least one polyester acrylate; B) at least 2% by weight of at least one alkoxysilane component, based on the total formulation; C) at least one acid-generating photoinitiator; D) optionally, one or more adhesion promoters; E) optionally, one or more photoinitiators for free-radical curing; and F) optionally, at least one selected from the group consisting of pigment and a different adjuvant, wherein the alkoxysilane component comprises at least one oligomeric siloxane component obtained by hydrolysis and condensation of at least one epoxy-functional silane of formula II, wherein: R R, R′ and R″ are alike or different and in each case are a hydrogen or a linear, branched, or cyclic, unsubstituted or substituted alkyl group having 1 to 6 C atoms; A and A′ are alike or different and in each case are a divalent alkyl group having 1 to 10 C atoms; and m is 0 or 1, optionally in the presence of at least one compound according to formula I wherein R R′ is methyl; groups R independently are a hydrogen or are a linear, branched, or cyclic alkyl group, having 1 to 6 C atoms; and n is 0 or 1.
