Claims:

What is claimed is:

1. Photopolymerization initiator selected from the group consisting of Mo or W complexes which under irradiations conditions photochemically reacts to release at least oneuncharged Lewis base, wherein the released uncharged Lewis base is 1,2-diazabicvclo[2,2,2]loctane. pyrrolidine, dimethylcyclohexylamine, or a mixture thereof.

2. A photopolymerization initiator selected from the group consisting of [Co(NH.sub.3).sub.4(SCN).sub.2][BPh.sub.4] [Co(en).sub.2(SCN).sub.2][BPH.sub.4] [Co(Py).sub.4(SCN).sub.2][BPh.sub.4] [Co(NH.sub.3).sub.2(SCN).sub.4][K][Co(NH.sub.3).sub.5(SR)][BPh.sub.4].sub.2 [Co(NH.sub.3).sub.4(SR).sub.2][BPh.sub.4] [Co(NH.sub.3).sub.5(OR)][BPh.sub.4].sub.2 [Co(NH.sub.3).sub.4(OR).sub.2][BPh.sub.4] [Mo(CO)(1,2-diazabicyclo[2,2,2]octane)] [W(CO).sub.5(dimethylcyclohexylamine)] and[W(CO).sub.5(1,2diazabicyclo[2,2,2]octane)].
