Abstract
An inkable sheet suitable for use as an ink jet recording sheet comprises a non-porous thermoplastics polymeric film substrate having on a surface thereof a porous, ink-absorbent, resin layer. The porous layer which comprises voids capable of absorbing and retaining an aqueous-organic ink-solvent medium by capillary action, may comprise a hydrophobic resin, a hydrophilic resin or a blend thereof, and may be bonded to a substrate, such as a film of polyethylene terephthalate, by an intermediate adhesive resin layer. The sheet is particularly suitable in the production of an imaged transparency for use in a transmission mode.
