description The invention relates to a method of increasing the dark storage stability of a UV-curable composition comprising a) at least one oligomer, co-oligomer, polymer or copolymer having at least one ethylenically unsaturated bond or a mixture thereof; or a mixture of at least one ethylenically unsaturated monomer with at least one oligomer, co-oligomer, polymer or copolymer having at least one ethylenically unsaturated bond; or at least one ethylenically unsaturated monomer or mixture of said monomers, and one or more α-hydroxycycloalkylphenyl ketone or bisacylphosphine oxide photoinitiators, which method comprises adding b) at least one stable sterically hindered nitroxyl free-radical or at least one compound of the benzofuran-2-one type or a mixture of the two compounds.
