ABSTRACT:
The present invention relates to a radiation curable resin composition which comprises epoxy (meth)acrylate, a monofunctional (meth)acrylate, a bifunctional (meth)acrylate having a specific structure, and a bifunctional (meth)acrylate obtained from an aliphatic dihydric alcohol having an oxyalkylene structure and (meth)acrylic acid and further contains a thermoplastic resin, thereby causing satisfactory adhesion to plastic substrates, sufficient shape retention, and excellent shape recovery properties, and satisfaction in moldability including casting efficiency and shape reproducibility, as well as a high refractive index and appropriateness for use as a lens sheet.
