PROBLEM TO BE SOLVED: To provide an epoxy resin blend hardly occurring hardening in early of blending while having a hardening rate equal to or more than that of conventional ones, and capable of curing completely and uniformly by increasing in a processing time at room temperature.SOLUTION: There is provided a blend of α) an epoxy resin and &bgr;) a mixture containing of 1) a hardening agent component a), 0.3 to 0.9 amine equivalent per epoxy equivalent and 2) a hardening agent component b). The component a) contains amine having a functional value≥2 and amine provides a hardening time of less than 24 hours at room temperature when mixed with the epoxy resin stoichiometrically, and the component b) contains a compound represented by the formula I. (I), where R1 to R3, R5 and R6 are organic group having 1 to 20 C atoms and hydrogen, R4 is an organic group having 1 to 20 C atoms or a -C(NH)NR5R6 group. |
