Provided is a printing medium particularly useful for inkjet printing. The printing medium is comprised of a substrate and a coating layer. The coating layer comprises porous particles, a resin binder and colloidal particles, with the colloidal particle being of a size that is greater than the size of the pores of the porous particles, but smaller than the interstitial pores created by the porous particles. The printing medium allows one to realize high optical density and high image resolution, while also offering good mechanical properties, fast drying, good waterfastness and consistent performance in different environments.

An improved cover material for hard- and soft-book covers is disclosed. The material comprises a conventional substrate, such as paper, and a coating that comprises an acrylic binder, the binder having a Tg of -10.degree. to 10.degree. C., and a filler system, the filler system comprising (a) about 2.0% to about 7.0% of silica or a silicate; (b) about 28% to about 38% of calcined clay; (c) about 20% to about 27% of titanium dioxide; and (d) about 30% to about 45% of a white filler pigment. The filler system may additionally comprise 3% to 7% of a pigmentary polymeric particulate. The laminate may also additionally comprise a protective top coat coated over the layer of cover material.

A sheet of fibrous web material having one textile-like surface and an opposite substantially smooth surface, a grain depth memory factor greater than 80, an apparent density in the range of about 4 to about 7 pound ream/caliper point in mils, a caliper (at a basis weight between about 50 and about 75 pounds/3000 square feet) greater than 0.008 inch, and a machine-direction sheet stretch of at least 5%. The invention includes a method of manufacturing the sheet comprising partially dewatering a wet fibrous web to about 30% to about 60% solids, conveying the web to a compression nip defined by a smooth-surfaced roll and a textured-surfaced fabric material, moving the fabric material at a speed of about 15% to about 35% less than the surface speed of the smooth-surfaced roll, compressing the web in the nip with a compression force between about 5 pounds/linear inch and about 100 pounds/linear inch, with an average pressure of between about 20 pounds per square inch and about 400 pounds per square inch in the compression nip, subjecting the fabric material to a tension on opposite sides of the compression nip with the tension on the fabric material entering the nip being greater than the tension on the fabric material exiting the nip, and drying the web.
