Method for producing laminate for configuring image display device, and image display device using the laminate

摘要

A method for producing a laminate for configuring an image display device is provided, capable of realizing simultaneously unevenness followability and anti-bubble reliability. A method for producing a laminate for configuring an image display device is proposed, comprising the following steps (1) and (2):;(1) The step of forming an adhesive composition into the form of a monolayer or a multilayer sheet, and by UV-crosslinking, primary-curing this thereby forming a pre-secondary curing transparent double-sided adhesive sheet.;(2) The step of layering two image display device-constituting members via the pre-secondary curing transparent double-sided adhesive sheet and then irradiating ultraviolet light from at least a first image display device-constituting member side, UV-crosslinking through this member and secondary-curing the pre-secondary curing transparent double-sided adhesive sheet.

1. A method for producing a laminate, the method comprising:
forming an adhesive composition into a form of a monolayer or a multilayer sheet; primary-curing the monolayer or multilayer sheet by UV-crosslinking to obtain a pre-secondary curing transparent double-sided pressure-sensitive adhesive sheet; layering two image display device-constituting members via the pre-secondary curing transparent double-sided adhesive sheet; and then irradiating ultraviolet light from a side of an image display device-constituting member, thereby UV-crosslinking and secondary-curing the pre-secondary curing transparent double-sided adhesive sheet through the member, wherein the adhesive composition comprises at least one selected from the group consisting of (a) a meth)acrylic monomer for polymerization or copolymerization of two different kinds of monomers, and (b) an acrylic acid ester polymer or acrylic acid ester copolymer, and wherein the adhesive composition further comprises at least one selected from the group consisting of an oligomer and a plasticizer.
