 | | Suitable photosensitive compositions may comprise a polymerization-initiating amount of at least a first UV-excitable photoinitiator, such as a UV-excitable photoinitiator selected from the group consisting of a benzoin derivative, benzil ketal, hydroxyalkylphenone, alpha-amino ketone, acylphosphine oxide, benzophenone derivative and a thioxanthone derivative. |
 | | Other photosensitive compositions may comprise a polymerization-initiating amount of at least a first visible light-excitable photoinitiator, such as a visible light-excitable photoinitiator selected from the group consisting of eosin, methylene blue, rose bengal, dialkylphenacylsulfonium butyltriphenylborate, a fluorinated diaryltitanocene, a cyanine, a cyanine borate, a ketocoumarin and a fluorone dye. |
 | | These photosensitive compositions may further comprise a co-initiating amount of at least a first co-initiator or accelerator, such as a co-initiator or accelerator selected from the group consisting of a tertiary amine, peroxide, organotin compound, borate salt and an imidazole. |
