Abstract

The present invention is intended to provide an adhesive composition for temporarily fixing which exhibits high adhesive strength and peeling property in water, and which is applicable to members having opaque area, and still which leaves no adhesive deposit on released members, so that it realize the excellent workability and environment. The present invention is a two-component composition for temporarily fixing members, comprising (A) a polyfunctional (meth)acrylate, (B) a mono-functional (meth)acrylate, (C) an organic peroxide, (D) a decomposition accelerator, (E) a polymerization initiator and (G) particulate matter, and composed of two-component system of a first agent and a second agent, said first agent containing at least said component (C) and said second agent containing at least said component (D), wherein cured body of said composition being used to bond members is brought into contact with water to be decomposed and release said members.
