摘要： Provided are a curing agent for epoxy resins, which is a curing agent capable of curing an epoxy resin at room temperature, and which can form a cured product (cured coating film) having excellent adhesion even to a substrate which is not in an environment completely dried, and an epoxy resin composition obtained using the same. A curing agent for epoxy resins, containing (a1) an aromatic amine, (a2) an aliphatic amine having an aromatic ring or a cycloalkane ring, and (a3) a curing accelerator, and an epoxy resin composition containing the curing agent and an epoxy resin.
