Abstract:
To provide a method for temporarily fixing an optical member suitable for processing of optical members, and an adhesive composition useful for such a method.An adhesive composition comprising (A) a polyfunctional (meth)acrylate, (B) a monofunctional (meth)acrylate and (C) a photopolymerization initiator, wherein the glass transition temperature of a cured resin obtained from the adhesive composition is from −50° C. to 40° C. A method for temporary fixing a member, which comprises bonding and temporarily fixing the member by means of the above adhesive composition, processing the temporarily fixed member, and immersing the processed is member in warm water of at most 90° C., thereby to remove a cured resin of the adhesive composition from the member.
