Embodiment 1

[0113] (preparation of adhesive)

[0114] 10 g of white polymer obtained in Production Example 1 as thermoplastic resin (b), 0.6 g of 3-ethyl-3(((3-ethyloxetane) as thermosetting monomer (c) -3-yl)methoxy)methyl)oxetane (manufactured by TOAGOSEI CO., LTD., trade name: "ARON OXETANE OXT-221") and 2.5 g of an epoxy group terminal coupling agent (Shin - manufactured by Etsu Chemical Co., Ltd., trade name: "KBM-403"), and as a curing catalyst, 0.4 g of 1,2-dimethylimidazole and 0.05 g of dibutyltin dilaurate were dissolved in 30 g of ring Pentanone thus provides the binder.

[0115] (Glass)

[0116] One surface of glass measuring 50 μm in thickness, 10 cm in length, and 4 cm in width was cleaned with methyl ethyl ketone, and then corona-treated and then epoxy-terminated coupling agent (manufactured by Shin-Etsu Chemical Co., Ltd. .Trade name: "KBM-403") for coupling treatment. The other surface of the glass is treated in the same way.

Embodiment 2

[0122] Except in the preparation of the adhesive, 3-ethyl-3(((3-ethyloxetan-3-yl)methoxy)methyl)oxetane (TOAGOSEI CO., LTD. manufacture, trade name: "ARON OXETANE OXT-221") was changed to 0.8 g, and epoxy group terminal coupling agent (Shin-Etsu Chemical Co., Ltd. manufacture, trade name: "KBM -403") was changed to other than 3 g, and a transparent substrate was obtained in the same manner as in Example 1.

Embodiment 3

[0124] (preparation of adhesive)

[0125] 0.3 g of 3-ethyl-3(((3-ethyloxetanyl-3-ethyl)methoxy)methyl)oxetane (TOAGOSEI CO., LTD., trade name: "ARON OXETANE OXT-221") and 2.0 g of epoxy-based terminal coupling agent (manufactured by Shin-Etsu Chemical Co., Ltd., trade name: "KBM-403") , and 0.15 g of 1,2-dimethylimidazole and 0.2 g of dibutyltin dilaurate as a curing catalyst were mixed in 10 g of polyarylate (manufactured by UNITIKA LTD., trade name: " M-4000", weight average molecular weight: 5×10 4 ) in a solution (concentration: 21 wt%) in cyclopentanone to provide a binder.

[0126] (Glass)

[0127] One surface of glass measuring 50 μm in thickness, 10 cm in length, and 4 cm in width was cleaned with methyl ethyl ketone, and then corona-treated and then epoxy-terminated coupling agent (manufactured by Shin-Etsu Chemical Co., Ltd. .Trade name: "KBM-403") for coupling treatment. The other surface of the glass is treated in the same way.

Abstract

Provided is an adhesive showing excellent adhesiveness even when the adherend is glass or a thermoplastic resin. This adhesive is for resin layer adherends containing glass and / or a thermoplastic resin (A), and contains a thermoplastic resin (b), thermosetting monomers (c), and a curing catalyst. As said thermoplastic resin (b), the adhesive contains an aromatic thermoplastic resin (b1) having a glass transition temperature (Tg) exceeding 200°C, and / or an alicyclic thermoplastic resin (b2) having a glass transition temperature (Tg) exceeding 200°C. The thermosetting monomers (c) are compatible with said thermoplastic resin (b), and the content ratio of the thermosetting monomers (c) is 5-50 parts by weight for 100 parts by weight of thermoplastic resin (b).

Description

technical field [0001] The invention relates to an adhesive and a transparent substrate. Background technique [0002] In recent years, weight reduction and thinning of display elements such as flat panel displays (FPDs: liquid crystal display elements, and organic EL display elements, etc.) Improvement in flexibility. Hitherto, glass substrates have been used as transparent substrates for display elements in many cases. The glass substrate is excellent in each of transparency, solvent resistance, gas barrier and heat resistance. However, when one attempts to achieve weight reduction and thinning of glass materials used to form any such glass substrates, the following problems arise. That is, the glass substrate shows a certain degree, but not sufficient, of bendability and insufficient impact resistance, and thus the glass substrate becomes difficult to handle. [0003] In order that the handleability of thin glass substrates can be improved, substrates in which a resin...
