Patent number: 8080292Abstract: A print medium is disclosed which includes a base paper containing a first side and a reverse side, and a coating layer disposed on at least the first side. The coating layer contains a mixture that includes about 10-90 weight percent of a first pigment comprising precipitated calcium carbonate particles, about 5-60 weight percent of a second pigment comprising particles of a liquid absorptive material having a larger size than the first pigment particles and having a different shape that of the first pigment particles, and about 1-50 weight percent of a third pigment comprising particles of a liquid absorptive high surface area material having a surface area of at least 50 m2/gram, and having a smaller size that both of the first and second pigments. Weight percents are by combined weight of the first, second and third pigments.Type: GrantFiled: October 15, 2008Date of Patent: December 20, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventor: Xi Zeng

Publication number: 20110274856Abstract: An article in the form of a paper substrate having a first surface and a second surface and an acid-resistant water-swellable substrate coating which provides an ink-receptive porous surface on at least one of the first and second surfaces. The substrate coating has an amount of an acid-resistant coating pigment sufficient to impart a Parker Print Smoothness value of at least about 4 to the at least one of the first and second surfaces and is dispersed in an acid-resistant water-swellable crosslinked polymer coating pigment binder matrix, with the coating pigment having from about 30 to 100% larger coating pigment particles with a mean particle size above about 1 micron in diameter. Also, a method for preparing such coated paper substrates.Type: ApplicationFiled: April 8, 2011Publication date: November 10, 2011Applicant: INTERNATIONAL PAPER COMPANYInventors: Michael F. Koenig, Kapil M. Singh
