| 摘要 |
Visible light cured polymerizable 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.
