Embodiment 1
[0159] Nitrogen gas was introduced into a reaction apparatus equipped with a stirrer, a thermometer, a reflux condenser, and a nitrogen introduction pipe, thereby replacing the air in the reaction apparatus with nitrogen. Then, 100 parts by weight of 2-ethylhexyl acrylate, 5.0 parts by weight of 8-hydroxyoctyl acrylate, and 60 parts by weight of a solvent (ethyl acetate) were added to the reaction device. Then, 0.1 part by weight of azobisisobutyronitrile as a polymerization initiator was dropped over 2 hours, and reacted at a temperature of 65°C for 6 hours to obtain the acrylic copolymer solution of Example 1 with a weight average molecular weight of 500,000. To this acrylic copolymer solution, 8.5 parts by weight of acetylacetone was added and stirred, and then 2.0 parts by weight of Coronate HX (Coronate HX, an isocyanurate of a hexamethylene diisocyanate compound), 0.1 parts by weight of titanium triacetylacetonate, and and stirring and mixing to obtain the binder composi...
Embodiment 2~6 and comparative example 1~3
[0161] Except that each composition of the adhesive composition of Example 1 was adjusted as described in Table 1 and Table 2, the same operation was carried out as in Example 1, and the adhesives of Examples 2-6 and Comparative Examples 1-3 were obtained. binder composition. In Table 1 and Table 2, the monomers contained (copolymerized) in the acrylic copolymer are (A), (B), (C), (G) and "carboxyl group-containing monomer".
