An anti-copy film is disclosed. The film has a light transmissive imageable substrate having opposing first and second surfaces. Each surface has an image receptive coating. Complementary positive and negative images are disposed on the first and second surfaces such that an imaged area on the first surface is in registration with a non-imaged area on the second surface. The anti-copy film appears substantially opaque when viewed orthogonally to and appears partially transparent when viewed obliquely to either the first or second surfaces.

Imaged anti-copy film

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.

Multicolor imaging using multiphoton photochemical processes

A method is provided for imparting images created with an inkjet printer to substrates. In accordance with the method, an image is imparted to an image receiving layer releasably disposed on a carrier sheet. An article can be provided, which is equipped with an adhesive patch on its surface. The image receiving layer is then brought into contact with the adhesive patch and, the carrier sheet is removed, thereby imparting an image to the substrate.
