Abstract: This invention relates to a fine powder-coated amine comprising a solid amine having a melting point equal to or higher than 50° C. and a mean particle size equal to or smaller than 20 μm. The fine powder-coated amine has an amount of heat in the second absorption peak measured by a differential scanning calorimeter equal to or less than 220 J/g, and the surface of the solid amine is coated with fine powder having a mean particle size equal to or smaller than 2 μm.
