Embodiment 1~9
[0128] The raw materials of the types shown in Table 1 were mixed at the composition ratio shown in Table 1 to prepare the resin compositions of Examples 1-9. The photocurability, tensile shear adhesive strength, and storage storage stability were evaluated as described later, and the results are shown in Table 1.

Embodiment 10~13
[0135] The raw materials of the types shown in Table 3 were mixed at the composition ratios shown in Table 3 to prepare resin compositions of Examples 10 to 13. The results of the evaluation are shown in Table 3.

[0138] 〔Photocurability evaluation〕
[0139] The rigid modulus under UV irradiation can be measured using a rheometer ("MCR-301" manufactured by Arton-Paar Co., Ltd.). The obtained resin composition was sandwiched from both sides by a circular plate with a diameter of 8 mm, while irradiating the resin composition with UV (illuminance at 365 nm: 150 mW / cm 2 ), while measuring at 25°C (±0.5°C) and a frequency of 10Hz. Within 200 seconds after the start of UV irradiation, the storage rigidity modulus G' increased to 1.00E+4 (1.00×10 4 ) or above was judged to be good, and marked with a symbol "○". On the other hand, those whose storage rigidity modulus G' was less than 1.00E+4 within 200 seconds after the start of UV irradiation were...
