PROBLEM TO BE SOLVED: To provide a polyamideamine curing agent which has low viscosity and by which a cured product having excellent strength, such as compressive strength, is obtained, an epoxy resin composition containing the curing agent, and a cured product of the composition. SOLUTION: The polyamideamine curing agent is obtained by reaction of a polyethylenepolyamine (a1), an aliphatic monocarboxylic acid (a2), and an aromatic monocarboxylic acid (a3), wherein the aliphatic monocarboxylic acid (a2) and the aromatic monocarboxylic acid (a3) are used with a molar ratio [a2/a3] in the range of 2/1 to 6/1. The epoxy resin composition containing the curing agent and the cured product of the composition are also provided. COPYRIGHT: (C)2011,JPO&INPIT |
