Reaction Conditions

Reaction Steps

In the same reaction vessel as in Example 1 was fed 275 g of the modified polyamine synthesized in Production Example 2 (corresponding to the modified polyamine based on 1 mol of metaxylene, 0.125 mol of polyethylene glycol, and 0.28 mol of epichlorohydrin), and then 163 g (0.88 mol) of 2-ethylhexyl glycidyl ether (epoxy equivalent of 186, produced by NOF Corporation, the trademark "Epiol EH") was added dropwise thereto over one hour at 80° C. in an atmosphere of nitrogen under stirring. After the completion of the dropwise addition, the reaction was carried out for one hour at a reaction temperature raised 100° C. Then, the vessel interior was cooled to 80° C., and then 200 g (1.47 mol) of metaxylylenediamine was added thereto. Then, a mixture of 282 g (0.743 mol) of epoxy resin in a liquid form of bisphenol A type (epoxy equivalent 190, produced by Yuka Shell Epoxy Co., Ltd., the trademark "Epicoat 828") with 236 g (1.79 mol) of butyl glycidyl ether (epoxy equivalent of 132, produced by NOF Corporation, the trademark Epiol B") was added dropwise thereto over one hour at 80° C.
