PRINTING PLATE PRECURSOR COMPRISING A LASER IMAGEABLE TUNED OPTICAL CAVITY THIN FILM
摘要
<p>A laser imageable tuned optical cavity thin film for use with a laser producing laser radiation at a laser wavelength comprising a flexible sheet of plastic having first and second surfaces serving as a film substrate. A thin film stack is disposed on the first surface of the film substrate and comprises a first vacuum-deposited metal layer carried by the first surface. It is also comprised of a dielectric layer deposited on the first metal layer. A second semi-opaque metal layer is vacuum deposited onto the dielectric layer. The thin film stack is tuned to provide maximum absorption at the laser wavelength.</p>
