Title:
METHOD FOR PRODUCING LAMINATE FOR FORMING IMAGE DISPLAY DEVICE USING TRANSPARENT DOUBLE-SIDED ADHESIVE SHEET
Document Type and Number:
Japanese Patent JP2023001155
Kind Code:
A
Abstract:
To propose a novel transparent double-sided adhesive sheet for image display devices that has an ultraviolet absorption function, which transparent double-sided adhesive sheet is used for primary sticking and, thereafter, can be cured for secondary sticking.SOLUTION: The present invention provides a method for producing a laminate for forming an image display device, which performs the following steps in order, using a transparent double-sided adhesive sheet formed from an adhesive resin composition containing a methacrylic copolymer (A), a crosslinking agent (B), a photopolymerization initiator (C) having an extinction coefficient of 10 mL/(g cm) or more at a wavelength of 405 nm, and an ultraviolet absorber (D) (where, excluding the case of using transparent double-sided adhesive sheet formed from an adhesive resin composition containing an acrylate copolymer, a mono-acrylate oligomer, a multi-acrylate oligomer having 2-5 acrylate functional groups per molecule, and a photoinitiator). [I] A step of laminating two image display device-forming members via the transparent double-sided adhesive sheet. [II] A step f irradiating the transparent double-sided adhesive sheet with light including a light beam with a wavelength in the visible light region to photo-crosslinking the same for curing.SELECTED DRAWING: None
