摘要： The object of the invention is to provide a resin composition suitably used for optical members, which is excellent in fine pattern transferability, releasability from a mold, and adhesion to a supporting base, as well as a multilayer optical member obtained by using the resin composition. To achieve this object, there is provided a resin composition comprising a urethane oligomer (A), a bifunctional monomer (B) and a polymerization initiator (C), wherein the urethane oligomer (A) is obtained by blending a diisocyanate compound having two isocyanate groups in a molecule, a hydroxylated methylene glycol compound and a caprolactone-modified (meth)acrylate compound such that the equivalent ratio between the isocyanate groups and the hydroxyl groups in the general formulae (I) and (II) (NCO/OH) is 0.8 to 1.2, as well as a multilayer optical member obtained by using the resin composition.
