Abstract: Paper coating compositions are provided for use with thermal ink-jet color printers, such as Hewlett-Packard Company's DeskJet® printer. The organic pigment present in the paper is modified by the addition of a metal-charge complex which causes anionic colorants in the ink to be precipitated on the surface of the paper. Printing any of the ink-jet ink sets onto the specially-prepared paper improves resolution, color retention, waterfastness, smear-fastness, image retention and image density while decreasing image bleed in ink-jet printing.
