Zusammenfassung:	The present invention relates to epoxy resin solidifying agent and a coating composition. The invention provides a epoxy resin solidifying agent which provides an excellent recoating property and external coating property after it is exposed for a long time and a coating composition with the solidifying agent. (A) The epoxy solidifying agent is prepared by adding the amide type reactant and the glycidyl ether compound, the amide type reactant is chosen from the polymine compound including polyoxyalkylenes polyamine for 25 to 75 mol percentage and carboxyl acid or the mixture of which; (B) a epoxy solidifying agent comprising the amide reactant of (B1) and the reactant of (B2), wherein (B1) is prepared by polyoxyalkylenes polyamine and carboxyl acid or the mixture of which, (B2) is prepared by adding other aliphatic polyamine or the mixture of which to the glycidyl ether compound. The invention also relates to the coating composition containing the epoxy solidifying agent A or B.
