The inhibitor contains a piperidinyl-N- or tetrahydropyrrole-N-oxyl cpd., opt. with a conventional inhibitor. Also claimed are cartridges, or bags with 2 or more compartments contg. the resin and hardener. Pref. the reaction resin contains 20 wt.% or more of a vinylester- or vinylester-urethane resin and can contain a methacrylate comonomer, as well as an accelerator (esp. a tert. amine) and also a conventional inhibitor (esp. a phenol, quinone or phenothiazine).
