Abstract
A negative-working, imageable element comprises a substrate and an IR-sensitive imageable layer comprising a dispersion of nanofibers of a preformed IR-sensitive polymer. The nanofibers can be composed of polyaniline, polypyrrole, or polythiophene. The IR-sensitive imageable layer containing the nanofibers can be imaged using infrared radiation and used for printing without further processing. Thus, both imaging and printing can be carried out on-press.
Claims20
A negative-working, imageable element comprising a substrate and having disposed thereon, an IR-sensitive imageable layer comprising a dispersion of nanofibers of a preformed IR-sensitive polymer,
- wherein said substrate comprises a metal or polymeric film support.
A method of forming an imaged element comprising:
- A) imagewise exposing an imageable element comprising a substrate and having disposed thereon, an IR-sensitive imageable layer comprising a dispersion of nanofibers of a preformed IR-sensitive polymer, to provide an imaged element with both imaged areas and non-imaged areas, and
- B) processing said imaged element on-press to remove said non-imaged areas.
