Problems solved by technology

However, if a resin composition with the same composition is used as the dam material and the filling material, there is a concern that the high viscosity of the dam material or the low viscosity of the filling material will be sacrificed.

[0029] [Method for producing laminate]

[0030] The manufacturing method of the laminated body which concerns on this embodiment has following process (A)-(D), and a process (C) includes heating a 2nd resin composition. In addition, as described in detail below, the second resin composition used in this production method contains a monofunctional monomer whose heating residue after heating at 60°C for 30 minutes is 95.0% or more, and after heating at 80°C for 3 hours The heating residual amount is more than 95.0%.

[0031] Step (A): Using the first resin composition, a photocurable second resin composition application region is formed on the surface of the first member.

[0032] Step (B): apply the second resin composition to the application area.

[0033] Step (C): The first member and the second member are bonded together through the second resin composition to fill the application area with the second resin composition.

[0034] Step (D): The second resin composition is ...

Abstract

Even when the same resin composition is used as the dam material and the filler material, the high viscosity of the dam material and the low viscosity of the filler material can coexist, resulting in good adhesion between components. This production method includes: a step (A) of forming a coating area 7 of the second resin composition 8 on the surface of the first member using the first resin composition; and a step of applying the second resin composition 8 to the coating area 7 (B); the step (C) of filling the coating area 7 with the second resin composition 8 by bonding the first member and the second member via the second resin composition; and irradiating the second resin composition 8 with light. and the step (D) of forming the cured resin layer 1 . Step (C) includes heating the second resin composition 8 . The second resin composition 8 contains a monofunctional monomer with a heating residual amount of 95.0% or more after heating at 60° C. for 30 minutes. The heating residual amount of the second resin composition 8 after heating at 80° C. for 3 hours was 95.0% or more.

Description

technical field [0001] This technique relates to a method for producing a laminate and a photocurable resin composition. This application claims priority based on Japanese Patent Application No. Japanese Patent Application No. 2017-037614 filed in Japan on February 28, 2017, and this application is incorporated herein by reference. Background technique [0002] Conventionally, a technique of bonding members together using a photocurable resin composition and fixing them with a light-transmitting resin layer is known. For example, in Patent Document 1, it is described that a photocurable resin composition is arranged between an image display member and a translucent member to form a resin composition layer, and the resin composition layer is irradiated with light to form a cured resin layer. method. Here, it is desired that the adhesiveness between the light-transmitting member and the image display member in the image display device be good. [0003] In addition, from the...
