Abstract
A multilayer imageable article with at least two layers including a multiphoton imageable composition. The composition includes a multiphoton-sensitive photoactive system and at least one of a dye and a dye precursor. The photoactive system includes a multiphoton sensitizer capable of simultaneously absorbing at least two photons, an electron acceptor capable of transformation to a dye-activating species upon interaction with the multiphoton sensitizer subsequent to absorption of at least two photons, and optionally an electron donor.
