Abstract
Polymeric composition suitable for preparing an ink receptive coating for a recording sheet and the recording sheet formed therefrom. The composition comprises a hydrolyzed copolymer formed from vinyl amide monomer units and vinyl ester monomer units. The recording sheets of the invention can be imaged by means of pen plotters on ink jet printers that utilize either water-based inks or solvent based inks. The ink receptive coating formed from the polymeric composition of this invention is resistant to fingerprinting and inhibits clogging of pen tips.
