摘要： An aqueous epoxy resin solution which is obtained by mixing an epoxy compound or an organic solvent solution thereof with either an amine compound represented by formula (1) or a solution thereof in water, an organic solvent, or a water/organic solvent mixture to react or polymerize the epoxy compound with the amine compound, adding water to the resultant epoxy resin solution, heating the mixture, and removing the organic solvent and the unreacted amine compound therefrom. In formula (1): NH2N(R )(R ), [R and R are the same or different, and each represents C1-6 alkyl or are bonded to each other to form C2-11 alkylene or a group represented by -R -N(R )-R -, wherein R and R are the same or different and each represents C1-6 alkylene and R represents C1-6 alkyl or amino].
