Provided are a temporal fixation method in processing of optical members and a resin composition suitable therefor. The present invention provides a composition which is characterized by comprising (A1) : a (meth)acrylate with a molecular weight of at least 500 having at least one (meth)acryloyl group at a terminal or in a side chain of a molecule, (B1) : a polyfunctional (meth)acrylate, (C1) : a (meth)acrylate other than (A1) and (B1), and (D1) : a photopolymerization initiator. The invention also provides a method for temporarily fixing a member, characterized by comprising bonding a member to temporarily fix it with use of the composition, processing the temporarily fixed member, and immersing the processed member in warm water of at most 90°C, thereby removing a cured resin of the composition. |
