Embodiment 1

[0163] Nitrogen gas was introduced into a reaction device equipped with a stirrer, a thermometer, a reflux cooler, and a nitrogen introduction pipe, and the air in the reaction device was replaced with nitrogen gas. Afterwards, in reaction unit with the methyl acrylate of 10 weight parts, the 2-ethylhexyl acrylate of 90 weight parts, the acrylate-8-hydroxyoctyl ester of 5.0 weight parts, the polypropylene glycol monoacrylate (n =12) Add 60 parts by weight of solvent (ethyl acetate) together. After that, 0.1 parts by weight of azobisisobutyronitrile as a polymerization initiator was added dropwise over 2 hours, and reacted at 65°C for 6 hours to obtain the acrylic polymer solution of Example 1 with a weight average molecular weight of 500,000. . After adding 8.5 parts by weight of acetylacetone to this acrylic polymer solution and stirring, 2.0 parts by weight of CORONATE HX (isocyanurate body of hexamethylene diisocyanate compound) and 0.1 part by weight of titanium triacetyl...

Embodiment 2～6 and comparative example 1～3

[0165] Except that the composition of the adhesive composition of Example 1 was set as described in Table 1 and Table 2, the adhesive agent combinations of Examples 2 to 6 and Comparative Examples 1 to 3 were obtained in the same manner as in Example 1. things. In Table 1 and Table 2, the monomers (to be copolymerized) contained in the acrylic polymer are (A), (B), (F), and "carboxyl group-containing monomers".
