The present invention relates to a photopolymer composition for hologram formation, comprising: a polymer matrix comprising a siloxane-based polymer and a (meth)acrylate polymer containing one or more reactive functional groups in the side chains, a holographic recording method, and an optical element.

A composition and article of manufacture comprising a crosslinked polymer and a method of crosslinking a polymer are disclosed. The crosslinked polymer includes a polysiloxane and at least two dimerizable hydroxycinnamic acid crosslinkers. The method includes obtaining a polysiloxane and at least two dimerizable hydroxycinnamic acid crosslinkers, reacting the polysiloxane and the crosslinkers to form a crosslinked polysiloxane, and dimerizing the at least two hydroxycinnamic acid crosslinkers.
