Method for producing laminate, and laminate

Abstract

The invention provides a laminating body manufacturing method and a laminating body. The laminating body is formed by bonding a laminating film utilizing light-cured resin on a to-be-bonded body with steps. Bubbles and white turbidity can be prevented by bonding the laminating film on the to-be-bonded body provided with steps on the surface. The manufacturing method of the laminating body includes a working procedure of preparing the light-cured resin, wherein the light-cured resin has an energy storage volume that is greater than 1*104Pa and less than 9*104Pa below 24 DEG C and 1Hz and contains, by weight 5 to 10 parts (B) at least one among acrylate monomer with hydroxyl (methyl), 1.5 to 1 part of (C) optic polymerization initiator and 0.2 to 0.8 part of (D) bifunctional cross-linking agent relative to 100 parts of (A) host polymer composed of acrylic acid resin whose acid value is 0 to 33.

Description

[0001] This application is a divisional application of an application with a filing date of August 8, 2013, an application number of 201310342667.5, and an invention title of "Manufacturing Method of a Laminated Body and a Laminated Body". technical field [0002] This invention relates to the manufacturing method of the laminated body which used the photocurable resin composition, and a laminated body. More specifically, the present invention relates to a method for producing a laminate in which a laminate film using a photocurable resin composition is bonded to an adherend, and the laminate, wherein the laminate film can follow printing steps Etc. to prevent the generation of air bubbles, and after UV irradiation in the durability test under high-temperature and high-humidity environmental conditions, no white turbidity occurs. [0003] In addition, the "printing level" in this specification means the thickness of the printed layer calculated from the surface of the substrat...

AI Technical Summary

Problems solved by technology

In the case of the adhesive composition described in Patent Document 5, there is no description of an adhesive composition that does not cause a cloudy adhesive layer under environmental conditions of 85° C. and 95% RH, and an adhesive using the composition. knot tape

In addition, since the alkyl (meth)acrylate monomer is excessively introduced, as shown in the example of Patent Document 5, after pouring the resin into the template, it is necessary to weaken the ultraviolet rays through glass and irradiate for a long time, etc., and the equipment must be repaired. improve

In addition, although it is described as an adhesive composition that does not cause cloudiness of the adhesive layer even under environmental conditions of 60°C and 90%RH, and an adhesive tape using the composition, it is necessary to irradiate weak ultraviolet rays for a long time. , so the production efficiency is poor

[0022] Thus, in the prior art, there is no known method for producing a laminated body and a laminated body in which a laminated film using a photocurable resin composition is bonded to an adherend having a step on the surface. Formed on the body, the laminated film can follow the steps between the front glass plate of the display as the adherend and the black frame of the light-shielding layer, and can prevent the generation of air bubbles during lamination. Moreover, even in very The adhesive layer (photocurable resin layer) does not become cloudy even under severe high-temperature and high-humidity environmental conditions, such as 85°C and 95%RH environmental conditions suitable for automotive displays
