Abstract
The present invention provides a method for manufacturing a laminate, comprising the steps of laminating two or more layers of polycarbonate resin film and/or sheet using a (meth)acrylate-based adhesive composition containing a (A) (meth)acrylate monomer, a (B) meth(acrylate) olygomer, an (C) acrylamide derivative, and a (D) silane compound and/or an (E) organophosphorus compound to form a laminate having a thickness of 0.1 mm to 30 mm; heating the laminate at 130° C. to 185° C. so that a temperature difference between a top surface and a bottom surface of the laminate is within 20° C.; and bending the post-heating laminate into a curved shape having a radius of curvature of 10 mm or greater.
