　実施例で用いた硬化触媒の融点は、比較例１の硬化触媒より高かった。比較例２は高融点ではあるが、分子量が小さいため、エポキシ樹脂などに溶解しやすく安定性に欠ける。
　樹脂組成物のポットライフの比較より、比較例では４時間ですでに硬化していたのに対し、実施例では、増粘率が２倍になるのがすべて８時間以上であった。 The melting point of the curing catalyst used in Examples was higher than that of Comparative Example 1. Although Comparative Example 2 has a high melting point, it has a low molecular weight, so it is easily dissolved in epoxy resins and the like, and lacks stability.
A comparison of the pot life of the resin composition revealed that the comparative examples were already cured in 4 hours, whereas the viscosity increase rate doubled in all the examples in 8 hours or longer.
　実施例における樹脂組成物は、１０分以内にゲル化し、十分な反応性および硬化性があった。 The resin composition in the example gelled within 10 minutes and had sufficient reactivity and curability.
　このように、本開示の硬化触媒は、フタルイミド骨格を有することにより、結晶性が高く、従来のエポキシ樹脂とイミダゾール誘導体を付加させたアダクト体よりも高融点であり、また本開示の硬化触媒によって、安定で、意図しない温度における硬化触媒の樹脂への溶解が起こりにくい樹脂組成物が得られる。  Thus, the curing catalyst of the present disclosure has a phthalimide skeleton, so it has high crystallinity and a higher melting point than the conventional adducts obtained by adding an epoxy resin and an imidazole derivative. , a stable resin composition is obtained in which the curing catalyst is less likely to dissolve in the resin at unintended temperatures.
