ABSTRACT:
Compositions that can be photopolymerized by a cationic initiator at an accelerated rate include at least one epoxy monomer, at least one cationic photoinitiator, and a photosensitizer/accelerator. The accelerator is a phenolic resole, or a compound having a structure according to the formulain-line-formulae description="In-line Formulae" end="lead"?R1(CR2R3OH)n,in-line-formulae description="In-line Formulae" end="tail"?wherein R1is selected from phenyl, polycyclic aryl, and polycyclic heteroaryl, each optionally substituted with one or more electron donating group substituted phenyl;R2and R3are independently selected from hydrogen, alkyl, aryl, alkylaryl, substituted alkyl, substituted aryl and substituted alkylaryl; andn is an integer from 1 to 10.
