Abstract: Crosslinkable compositions including a (meth)acrylate polymer comprising an alkyl (meth)acrylate monomer; an acylphosphine oxide photoinitiator; and a crosslinking monomer, the crosslinking monomer comprising at least two terminal groups selected from the group consisting of allyl, methallyl, or combinations thereof. Methods of preparing such crosslinkable compositions and articles including such crosslinkable compositions are disclosed.

Abstract: Provided are crosslinkable compositions comprising a (meth)acrylate polymer, where the polymer has a glass transition temperature no greater than 30° C.; a crosslinking agent, the crosslinking agent comprising a photo-active Type II photoinitiator and a polymerizable group selected from the group consisting of (meth)acrylate, allyl, and combinations thereof; and a UV absorbing material represented by the structure (I) where each of X1, X2, X3, and X4 is independently a hydrogen atom, a hydrocarbyl group including 1 to 15 carbon atoms, preferably 12 carbon atoms, or a heterohydrocarbyl group including 1 to 15 carbon atoms, preferably 12 carbon atoms.
