Copying element, useful as base for photographic print material or ink-jet or thermal dye transfer printing, includes integrated oriented sheet with porous polyester between nonporous polymer layers

摘要

In a copying element with an integrated, oriented polymer sheet bonded to the front of a paper substrate, the polymer sheet consists of = 3 layers, i.e. layer(s) of porous polyester polymer between an upper non-porous polymer layer containing white pigment and a lower non-porous polymer layer. It also has oriented polymer sheet(s) on the back.
