LIGHT TRANSMISSION ELECTROMAGNETIC WAVE SHIELDING LAMINATE EXHIBITING EXCELLENT BENDABILITY, AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a light transmission electromagnetic wave shielding laminate which exhibits excellent bendability and does not cause production of bubbles, whitening or peeling by degradation or decomposition of an adhesion layer even under high temperature bending conditions.

SOLUTION: In a laminate having a thickness of 0.1-30 mm formed by laminating a polycarbonate base on one side or both sides of an electromagnetic wave shield layer by using a (meta)acrylate based adhesive composition exhibiting excellent bendability and containing (A) a (meta)acrylate monomer, (B) a (meta)acrylate oligomer and (C) an acrylamide derivative, (D) a silane compound and/or (E) an organic phosphorus compound, the laminate is heated at 130-160°C while confining the vertical surface temperature difference within 20°C, and then the laminate is bent to have a curved surface with a curvature radius of 10 mm or more.
