Photopolymerizable compositions are provided which are the reaction products of a vinyl ether, a photoinitiator system comprising an iodonium salt, a visible light sensitizer and an electron donor compound. These monomeric/oligomeric compositions may also include epoxides, polyols, spiroorthocarbonates. One embodiment of the present invention is a polymerizable composition comprised of a vinyl ether, a spiroorthocarbonate, and a photoinitiator system. Another embodiment of the present invention is a polymerizable composition comprised of a vinyl ether, an epoxide, a polyol, and a photoinitiator system. Still another embodiment of the present invention is a polymerizable composition comprised of a vinyl ether, an epoxide, a polyol, a spiroorthocarbonate, and a photoinitiator system. Still further, another embodiment of the present invention is certain novel spiroorthocarbonate compounds. Each of these novel spiroorthocarbonate compounds include at least one epoxy group as a substituent.

L'invention concerne des compositions photopolymérisables, produits de réaction d'un éther vinylique, et un système photoamorceur comprenant un sel d'iodonium, un sensibilisateur à la lumière visible, et un composé donneur d'électrons. Ces compositions monomère/oligomère peuvent également comprendre des époxydes, des polyols, et des spiro-ortho-carbonates. Une réalisation de la présente invention consiste en une composition polymérisable comprenant un éther vinylique, un spiro-ortho-carbonate, et un système photoamorceur. Une autre réalisation de la présente invention consiste en une composition polymérisable comprenant un éther vinylique, un époxyde, un polyol, et un système photoamorceur. Une autre réalisation de la présente invention consiste en une composition polymérisable comprenant un éther vinylique, un époxyde, un polyol, un spiro-ortho-carbonate, et un système photoamorceur. Une autre réalisation de la présente invention consiste en certains nouveaux composés spiro-ortho-carbonates. Chacun de ces nouveaux composés spiro-ortho-carbonates comprend au moins un groupe époxy en tant que substituant.
