Abstract
The present invention provides: PA0 (1) a one-packed epoxy resin composition comprising (A) an epoxy resin having two or more epoxy groups in its molecule and a number average molecular weight of 250 to 4,500, (B) a ketimine compound, (C) a dehydrating agent, and (D) at least one modified epoxy resin (d-1) selected among urethane-modified epoxy resins, amine-modified epoxy resins and dimer-modified epoxy resins and/or a resin (d-2) which has a softening point of 60.degree. C. or above and is at least one member selected among xylene resins, ketone resins, coumarone resins and petroleum resins; PA0 (2) a one-packed anticorrosive paint composition comprising the above one-packed epoxy resin composition and (E) a zinc dust in such an amount as to be present in a proportion of 20 to 95 wt. % in the heat-cured coating film; and PA0 (3) a coating method comprising the steps of undercoating the surface of a substrate and conducting topcoating, wherein the above one-packed epoxy resin composition or the above anticorrosive paint composition is used as the undercoating composition.
