Abstract
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.
