<p>The present invention is directed to new, energy-efficient, photoinitiators having the following formula: whrein Z each independlently represent the formula (II) wherein R1, R2, R3 and R4 each independently represent hydrogen, an alkyl group having from one to six carbon atoms, an alkoxy group having from one to six carbon atoms, or a halogen-substituted alkyl group; R5, R6, R7 and R8 each independently represent an alkyl group having from one to six carbon atoms, an aryl group, or a halogen-substituted alkyl group having from one to six carbon atoms; wherein R9 represents (R10)2O or (R10)3N, wherein R10 represents H or an alkyl group having from one to eight carbon atoms; and wherein R11 represents H, an alkyl group having from one to eight carbon atoms, a benzyl group or an aralkyl group. The present invention is also directed to a method of generating a reactive species, methods of polymerizing polymerizable materials, methods of curing an unsaturated oligomer/monomer mixture, and methods of laminating using the photoinitiators 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.</p> |
