The invention features a photopolymerizable composition that comprises a cationically polymerizable resin, and a photoinitiator system comprising an iodonium salt, a visible light sensitizer, and one or more anthracene-based compounds as electron donors. Electron donor combinations used in the invention include multiple substituted anthracene compounds or a combination of at least one substituted anthracene compound with unsubstituted anthracene.
La présente invention concerne une composition photopolymérisable faite d'une résine à polymérisation cationique et d'un système photo-amorceur. Ce dernier comprend un sel, l'iodonium, un photosensibilisant en lumière visible, et un ou plusieurs composés donneurs d'électrons à base d'anthracène. Les combinaisons de donneurs d'électrons utilisées pour l'invention incluent de multiples composés anthracène substitué, ou une combinaison de l'un au moins de ces composés anthracène substitué avec un anthracène non substitué.
