| 摘要 |
The present invention is directed to new, energy-efficient, photoinitiators having general formula (I) wherein X~1 is a conjugated system such as one or more aryl groups or substituted aryl groups; Z~1 is -O, -S, an alkyl group having from one to six carbon atoms, an ester moiety, a ketone moiety, an amine moiety, an imine moiety, an ether moiety, an aryl or substituted aryl group, a metal or non-metal, or a metal or non-metal containing group, such as a zinc-containing group or a boron-containing group, respectively; and M~1 i s an alkyl group, a substituted alkyl group, or forms a five member ring with Z~1. The present invention is also directed to a method of generating a reactive species, which includes exposing one or more photoinitiators to radiation to form one or more reactive species. Also described are methods o f polymerizing polymerizable materials, methods of curing an unsaturated oligomer/monomer mixture, and methods of laminating using the photoinitiator s of the present invention. In addition, the present invention is directed to ink compositions, adhesive compositions and resins, and methods of printing using the above-described photoinitiators.
