The present invention provides a method for producing a laminate, and a laminate. The laminate is produced by bonding a laminate film to an adherent having a stepped shape on the surface thereof, wherein the laminate film is produced by using a photo-hardening resin. When the laminate film is bonded to the adherent having a stepped shape on the surface thereof, the generation of bubbles can be prevented. When a durability test is performed on the photo-hardening resin under a high temperature (85°C) and high humidity (85%RH) condition by using an oven after ultraviolet rays are irradiated and even when the photo-hardening resin is taken out of the oven, it does not have white turbidity. The laminate comprises: (A) 100 parts by weight of a main polymer including an acrylic resin having an acid value of 0-33; (B) 5-10 parts by weight of at least one kind from hydroxyl group-containing methacrylic monomers; (C) 0.5-1 parts by weight of a photopolymerization initiator; and (D) 0.2-0.8 parts by weight of a difunctional cross-linker that is equivalent to or less than 0.1 of a cross-linking point of the polymer. The photo-hardening resin has a storage modulus (G′) of 1×10^4 Pa or more but less than 9×10^4 Pa under 24°C and 1 Hz. |
