PHOTOCURABLE ADHESIVE COMPOSITION SUITABLE FOR ADHESION OF ENGINEERING PLASTIC, OPTICAL PART ASSEMBLED BY USING THE SAME AND ASSEMBLING METHOD OF OPTICAL PART USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: a photocurable adhesive composition exerting excellent adhesive characteristic in the adhesion of engineering plastics; optical parts assembled by using the same; and a method for assembling optical parts using the same.

SOLUTION: (1) This photocurable adhesive composition includes (a) an oligomer having a photocurable functional group, (b) a long-chain hydrocarbon-based (meth)acrylate monomer and (c) a cyclic (meth)acrylate monomer. (2) The optical parts are assembled by using the photocurable adhesive composition. (3) The method for assembling optical parts includes a step of applying the photocurable adhesive composition to the adhesion site of an engineering plastic constituting the optical parts, and bonding the adhesion site.
