<P>PROBLEM TO BE SOLVED: To provide an amine composition for an epoxy curing agent that has low reactivity with epoxy resins and gives an epoxy resin cured product having excellent mechanical strength, to provide an epoxy resin composition containing the same, and to provide an epoxy resin cured product obtained from the epoxy resin composition. <P>SOLUTION: The amine composition for an epoxy curing agent includes: an alkylated polyalkylene polyamine (a) having, in the molecule thereof: one or two types of substituents selected from the group consisting of 1-6C N-alkylated amino group, an amino group (H<SB POS="POST">2</SB>N-), and an imino group (-NH-); and four active amine hydrogen atoms; an alkylated polyalkylene polyamine (b) having, in the molecule thereof: one or two types of substituents selected from the group consisting of 1-6C N-alkylated amino groups, an amino group (H<SB POS="POST">2</SB>N-), and an imino group (-NH-); and three active amine hydrogen atoms; and an alkylated polyalkylene polyamine (c) having, in the molecule thereof: one or two types of substituents selected from the group consisting of 1-6C N-alkylated amino groups, an amino group (H<SB POS="POST">2</SB>N-), and an imino group (-NH-); and two active amine hydrogen atoms, wherein (a) is 0.01-5 wt.% to (a)+(b)+(c), (c) is 0.5-40 wt.% to (a)+(b)+(c), and the remainder of (a)+(b)+(c) is (b). <P>COPYRIGHT: (C)2013,JPO&INPIT |
