The present invention provides an organic carboxylate composition that has long
working life, cures epoxy resins, and improves adhesive properties, and also provides
a method for producing the same. An organic carboxylate composition, obtained by
heating and mixing a basic silane coupling agent and an amine compound with a softening
point or melting point of 40 C. or greater together with an organic carboxylic
acid; a method for producing the same; an additive for epoxy resin that contains
this as the active ingredient thereof; and an epoxy resin composition containing
the same. The basic silane coupling agent should preferably be a specific imidazole-group
containing silane coupling agent, amino group-containing silane coupling agent,
dialkylamino group-containing silane coupling agent, monomethylamino group-containing
silane coupling agent, benzimidazole group-containing silane coupling agent, benzotriazole
group-containing silane coupling agent, and pyridine ring-containing silane coupling agent.
