ABSTRACT:
Thermosettable ethylenically unsaturated resins are rendered storage stable by the addition of at least one 1,4-naphthoquinone substituted on the 2 or 3 or both the 2 and 3 positions. The reactivity of these storage stable resins with curing agents is not unacceptably reduced by the presence of the stabilizer.
