To avoid problems, such as formation of a blushed or spotted surface and insufficient crosslinking, encountered during coating especially at a low temperature and high humidity by using a specified curing agent component as the curing agent for an epoxy resin.

This invention provides an amino-containing curing agent component for an epoxy resin, wherein the amino-containing curing component is a condensate of a di- or poly-hydroxy aromatic compound (A) with a polyamine (B). This component should have a ratio of component A to component B of 10.0:1.0(mol/mol) to 1.0:10.0(mol/mol). Component A is exemplified by 2,2'- or 4,4'-dihydroxydiphenyl or 2,2'- and 4,4'-dihydroxydiphenyl ether. Component B is exemplified by 1,2-diaminoethane or 1,2-diaminopropane.
