Problem: Thickness and high transparency with flow properties before irradiation, with sufficient fluidity and sufficient initial adhesion to the adherend, and with sufficient hardness (particularly high storage modulus) after irradiation The manufacturing method of the laminated body containing the hardening adhesive sheet of this. Solution: A method of manufacturing a laminate comprising a first substrate, a second substrate, and a cured adhesive sheet disposed between the first substrate and the second substrate, the method comprising: Forming a radiation curable adhesive sheet precursor into a sheet, the precursor comprising a polymer / monomer mixture comprising a partially polymerized (meth) acrylic monomer and short wavelength radiation below the first wavelength; A monomer having a radiation reactive site to be activated and a photoinitiator that initiates polymerization of the polymer / monomer mixture and the monomer having the radiation reactive site by radiation having a wavelength longer than the first wavelength. And a step of irradiating the precursor with radiation having a wavelength longer than a predetermined wavelength to polymerize the radiation curable adhesive sheet precursor to form a radiation curable adhesive sheet, and a radiation curable adhesive sheet, Placing the second substrate adjacent to at least one surface of the substrate, placing the second substrate adjacent to the radiation curable adhesive sheet, and applying heat and / or pressure to the radiation curable adhesive. A step of adding to the sheet, and a step of irradiating the radiation curable adhesive sheet with radiation containing short wavelength radiation of the first wavelength or less to obtain a cured adhesive sheet. |
