Abstract
Provided is an epoxy-amine adduct. The epoxy-amine adduct is a compound that may be a compound I containing two or more amino groups per molecule, a compound corresponding to the compound I, except being modified with a compound II-1 containing two or more (meth)acryloyl groups per molecule, a compound corresponding to the compound I, except being modified with a lactone II-2, or a salt of the compound I. The compound I is an adduct between an epoxide (A) containing two or more cycloaliphatic epoxy groups per molecule and an amine (B) containing two or more amino groups per molecule. The compound I includes a constitutional unit represented by Formula (I) and a constitutional unit represented by Formula (II) and contains amino groups at both ends. Formulae (I) and (II) are expressed as follows:
