Abstract
Photocurable compositions are provided which can be cured with ultraviolet light at a wave length greater than 300 nm. The photocurable compositions are based on the use of cationically polymerizable organic materials, for example, an epoxy resin and a photoinitiator in the form of a dialkylphenacyl sulfonium salt or hydroxyaryldialkyl sulfonium salt which have been sensitized with a particular dye sensitizer.
