Document Type and Number:
WIPO Patent Application WO/2008/018252
Kind Code:
A1
Abstract:
Disclosed is a method for temporarily fixing a member which is suitable for processing an optical member. Also disclosed is an adhesive composition suitably used for such a method. Specifically disclosed is an adhesive composition containing a polyfunctional (meth)acrylate (A), a monofunctional (meth)acrylate (B) and a photopolymerization initiator (C). This adhesive composition is characterized in that a cured product obtained therefrom has a glass transition temperature of from -50˚C to 40˚C. Also specifically disclosed is a method for temporarily fixing a member which is characterized in that the member is temporarily fixed by being bonded with the adhesive composition, and after processing the temporarily fixed member, the processed member is immersed into warm water at a temperature of not more than 90˚C for removing the cured product of the adhesive composition from the processed member.
