| 摘要 |
<p>This invention relates to photopolymerizable compositions comprising an ethylenically unsaturated organic compound and a visible light photosensitizing composition comprising a combination of Mn2 (C0)10 and a co-catalyst selected from the group consisting of a compound characterized by the formula WHEREIN R1 is -H, -Br, or -CH3, R2 is -H or -CH3, and R3 is -H or -CH3; cumene; diisopropyl benzene; alkyl mercaptans containing from 10 to 16 carbon atoms; thiourea; and mixtures thereof and to polymerized products thereof. The invention also provides a process for photopolymerizing ethylenically unsaturated organic compounds with visible light in the range of 4,000 to 7,000 angstroms.</p> |
