    • PROBLEM TO BE SOLVED: To provide an inhibitor which stabilizes the gelation time for a methacrylate resin-base two-component thermosetting resin to polymerize free-radically, where the inhibitor ensures the stability in gelation time of the thermosetting resin during storage as well as the reactivity, endurance, and quality under a low temperature.
      SOLUTION: The two-component thermosetting resin comprises a resin component (A) and a curing component (B), wherein the resin component (A) comprises at least one radical-curable ethylenic unsaturated compound for a curable constituent material (a), an agent (b) for regulating reactivity and gelation time, and at least one comonomer (c), the curing component (B) contains a curing agent for the resin component (A) and is positioned apart from the (A) to avoid itself from the reaction with the (A); and the resin component (A) comprises a brenz-catechin (catechol) derivative of general formula (I) for the agent (b) for regulating the reactivity and gelation time of the (A).
