A multicolor ink jet recording paper with improved dimensional stability for wide format printing is achieved by applying to at least one side of a paper support a dimensional stability improving layer containing polyethylene oxide polymer or copolymer. A suitable ink receptive layer is applied to the thus coated paper. The dimensional stability layer can be applied on the opposite side of the support as the ink receptive layer or as an underlayer of the ink receptive layer, and can be applied on both sides of the paper support. The ink jet recording paper possesses a short dry time, provides superior image quality, and is free of print defects typical in wide format paper bond printing.

Recording ink jet paper with improved dimensional stability

The present invention relates to ink-jet recording media suitable for use with dye and pigmented inks. The media comprise a substrate coated with at least two ink-receptive layers. The upper layer comprises a modified poly(vinyl alcohol) compound and plasticizer, particularly a maleic or itaconic acid-modified poly(vinyl alcohol). The first ink-receptive layer may comprise a partially hydrolyzed poly(vinyl alcohol). The media can record high quality multi-colored images with minimal inter-color bleeding and pigmented ink cracking.
