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: 

Epoxy-amine adduct, thermoplastic resin composition, sizing agent, sizing agent coated carbon fiber, and fiber-reinforced composite material

Provided are: a water-absorbing resin composition and a laminate using the resin composition. The resin composition is capable of giving a transparent anti-fog coating excellent in properties such as appearance, coatability, anti-fog properties, water resistance, and heat resistance. Specifically, a resin composition includes a specific (meth)acrylamide copolymer (A) in combination with at least one bifunctional or higher (meth)acrylate compound (B), in which the (meth)acrylamide copolymer (A) is copolymerized from a (meth)acrylamide monomer with another monomer. This resin composition provides an active-energy-ray-curable water-absorbing resin composition and a laminate using the resin composition, each having excellent anti-fog properties.
