Recording sheets

An imaged recording sheet which comprises a substrate and an image receiving coating situated on at least one surface of the substrate, said coating containing an additive selected from the group consisting of macrocycles, porphines, and mixtures thereof, said image receiving coating containing an image applied from an aqueous ink.

A process which comprises applying an aqueous recording liquid in an imagewise pattern to a recording sheet which comprises a substrate and an image receiving coating situated on at least one surface of the substrate, said coating containing an additive selected from the group consisting of macrocycles, porphines, and mixtures thereof, said image receiving coating being suitable for receiving images of an aqueous ink.

A printing process which comprises (1) incorporating into an ink jet printing apparatus containing an aqueous ink a recording sheet which comprises a substrate and an image receiving coating situated on at least one surface of the substrate, said coating containing an additive selected from the group consisting of macrocycles, porphines, and mixtures thereof, said image receiving coating being suitable for receiving images of an aqueous ink, and (2) causing droplets of the ink to be ejected in an imagewise pattern onto the recording sheet, thereby generating images on the recording sheet.

A recording sheet consisting essentially of (a) a paper or transparent polymeric material substrate, (b) an image receiving coating situated on at least one surface of the substrate, said coating containing an additive selected from the group consisting of porphines and mixtures thereof, said image receiving coating being suitable for receiving images of an aqueous ink, (c) an optional binder, (d) an optional filler, (e) an optional antistatic agent, and (f) an optional biocide.
