Abstract
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.
Claims5
A method of manufacturing a recording medium having a paper support with a front surface and back surface comprising the following steps, in sequence:
- (a) coating the back surface of the paper support with a dimensional stability-improving composition comprising polyalkylene glycol,
- (b) coating the front surface of the paper support with an underlayer comprising polyalkylene glycol, and
- (c) coating an ink-receptive composition comprising poly(vinyl alcohol), poly(vinyl pyrrolidone), and particulate onto the underlayer on the front surface of the paper support.
