An object of the present invention is to improve the stability of an ethylenically unsaturated compound having an isocyanate group in the molecule by preventing a polymerization, a multimerization reaction and a discoloration reaction of the ethylenically unsaturated compound. The present invention relates to a stabilizing composition for an isocyanate group-containing ethylenically unsaturated compound, comprising: an isocyanate group-containing ethylenically unsaturated compound (A) which comprises one or more isocyanate groups and one or more ethylenically unsaturated groups in the molecule; and a stabilizing agent (B) which is a compound in which at least one of the ethylenically unsaturated groups in the compound (A) is replaced with an alkyl halide group or an amino alkyl group which may have a substituent.
