Optical resin composition, optical resin material using the same, optical filter for image display device, and image display device

摘要

An optical resin composition that is transparent, has suitable adhesion and necessary impact absorption for protection of an image display device etc., not affecting constituent materials of a image display panel, and being excellent in reliability, can be used to provide an optical resin material using the same. The optical resin composition contains (A) a first acrylate derivative that is a compound having one polymerizable unsaturated bond in its molecule, (B) a second acrylate derivative that is a compound having two or more polymerizable unsaturated bonds in its molecule, and (C) an acrylate derivative polymer, and an optical resin material produced by curing reaction of the optical resin composition.
