Title:
MULTICOLOR IMAGING USING MULTIPHOTON PHOTOCHEMICAL PROCESSES
Document Type and Number:
WIPO Patent Application WO2001096952
Kind Code:
A3
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.
