Problems solved by technology

However, when the liquid adhesive is applied by the roll, the remaining adhesive will seep out and stain the equipment
In addition, problems such as entrapment of air bubbles and difficulty in obtaining uniform thickness of the adhesive layer may occur.

preparation example Construction

[0118] The preparation method of the adhesive composition of the present invention is not particularly limited, for example, the polyalkylene oxide addition polyfunctional epoxy compound (a) represented by the above general formula (A), polyfunctional (methyl) Acrylate monomer (b), photoacid generator (c) and additives are prepared by conventional methods such as stirring until uniform. It should be noted that, in order to prevent the decomposition of the photoacid generator (c), it is preferably prepared under light-shielding conditions.

[0119] In addition, in order to prevent the decomposition of the photoacid generator (c), the adhesive composition of the present invention after preparation is also preferably stored in a light-shielded manner.

[0120]

[0121] The bonding method of the adherends A and B using the adhesive composition of the present invention includes the following steps A and B in this order.

[0122] Step A: a step of applying the adhesive compositio...

Embodiment 1

[0150] According to the mass ratio of Table 1, RikaresinBEO-60E (trade name, manufactured by Nippon Chemical Co., Ltd.) as a polyalkylene oxide addition polyfunctional epoxy compound (a), as a polyfunctional (meth)acrylate monomer ( b) A-NOD-N (trade name, manufactured by Shin-Nakamura Chemical Industry Co., Ltd.), CPI-200K (trade name, manufactured by San-Apro Corporation) as a photoacid generator (c), were stirred until uniform, and viscous Adhesive composition.

[0151] The prepared adhesive composition was applied to a PET film with a thickness of 25 μm (trade name “G2”, manufactured by Teijin DuPont Co., Ltd.) with a thickness of 20 μm, and an ultraviolet irradiation device (trade name: US5-0151, EYEGRAPHICS manufactured by the company), at 50mW / cm 2 Irradiate for 60 seconds (irradiation dose: 2000mJ / cm 2 ) ultraviolet light. Furthermore, 1 hour after the end of the ultraviolet irradiation, a PET film (trade name "G2", manufactured by Teijin DuPont Co., Ltd.) with a th...

Embodiment 2～10、 comparative example 1～3

[0153]In Example 1, except that the components of the adhesive composition were replaced with the types and mass mixing ratios described in Table 1 below, Examples 2 to 10 and Comparative Example were prepared in the same manner as in Example 1. 1 to 3 adhesive compositions. Except for using the obtained adhesive composition, it was obtained in the same manner as in Example 1. figure 1 The bonded film (1) and the film for the test of the composition described in .

[0154] Here, all the adhesive compositions prepared in Examples 1 to 10 were liquid at 23°C.

Abstract

An adhesive composition comprising an adherend method for bonding the adhesive composition and a method for producing the layered product, wherein the adhesive composition contains a polycyclic ring represented by the following general formula (A) (A), a polyfunctional (meth) acrylate monomer (b) and a photoacid generator (c). (In the above formula, R represents a lower alkylene group (for example, an alkylene group having 1 to 4 carbon atoms), and a lower alkylene group (for example, an alkylene group having 1 to 4 carbon atoms) , X represents a divalent linking group or a lower alkylene group having a cyclic structure of 6 to 20 carbon atoms (for example, an alkylene group having 1 to 4 carbon atoms), and m and n are each independently 0 or more Of the integer).

Description

technical field [0001] The present invention relates to an adhesive composition, a method for joining adherends using the adhesive composition, and a method for producing a laminate. Background technique [0002] In the field of displays in recent years, due to the development of technologies such as weight reduction and thinning of displays, and resinization, displays that are not easily broken even if dropped, bendable / rollable displays, and stretchable Development of displays, etc. [0003] For example, examples of bendable displays include liquid crystal displays, organic EL displays, and electronic paper. These displays are produced by bonding components such as touch panels, protective films, and polarizers to the display substrate. Therefore, adhesive materials characterized by high flexibility and bending resistance have been proposed as adhesives for laminating display substrates or components. [0004] However, an ultraviolet absorber is mixed in an optical film...
