Abstract
The present disclosure relates to a hologram recording medium having one surface with a higher surface energy than a polymer resin layer containing at least one polymer selected from the group consisting of triacetyl cellulose, alicyclic olefin polymer and polyethylene terephthalate, a hologram recording medium wherein the surface energy of any one surface is 50 mN/m or more, and an optical element comprising the hologram medium.
Claims11
A hologram recording medium having one surface with a higher surface energy than a polymer resin layer of a base substrate containing at least one polymer selected from the group consisting of triacetyl cellulose, alicyclic olefin polymer and polyethylene terephthalate,
- wherein the hologram recording medium has one surface with a surface energy of at least 50 mN/m,
- wherein the hologram recording medium comprises a polymer layer which
- includes a cross-linked product between a polymer matrix including a (meth)acrylate-based (co)polymer having a silane-based functional group in a branched chain, and a silane crosslinking agent;
- and a photoreactive monomer.
