Visible light cured polymerizable thiol-ene compositions comprising at least one monomer or oligomer having a plurality of free-radically polymerizable ethylenically unsaturated groups, at least one compound having a plurality of thiol groups, at least one acyl phosphine oxide photoinitiator and optional adjuvants, such as stabilizers, pigments, fillers, and polymerization inhibitors are disclosed. The polymerized compositions are useful, as protective coatings, or anti-chip coatings or as repair putties on exterior coated substrates such as plastics, wood and metal, especially for the automotive and marine industries.

[ What is claimed is:] [1.] A polymerizable composition comprising:(a) a mixture of a vinyl monomer or oligomer and a (meth)acrylic monomer or oligomer;(b) at least one compound having a plurality of thiol groups; and(c) an acyl phosphine oxide photoinitiator blended with an .alpha.-hydroxyketone, with absorption in the visible range sufficient to initiate photopolymerization.
