Abstract: Coated substrates are made from colored paper coated with a coating comprising silica or fumed metal oxide, such as precipitated silica, colloidal silica, fumed silica or fumed metal oxide. An opaque coating is formed which improves the L* and b* values of the colored paper. Images printed onto the paper show improved characteristics, such as a reduction in wick or bleed, or an improved color gamut.

Abstract: Coated substrates include a substrate coated with a coating composition comprising a metal oxide, a binder and optionally a mordant and a crosslinker for the binder. The substrate may be paper, such as commodity paper, and the metal oxide may be a fumed metal oxide or a colloidal metal oxide. The coating may be non-glossy and may be applied at a low coat weight. Methods for making coated substrates are also disclosed. The coating may be applied to the substrate during manufacture of the substrate, for example the coating may be applied to paper using a size-press machine during its manufacture.

Abstract: The described invention is an unique universal ink jet media. The invention incorporates a unique barrier layer based upon UV or EB curable chemistry which replaces common polyethylene extruded bases. The invention also incorporates multiple ink receptive layers. The first layer is based upon gelatin and/or polyvinyl alcohol (PVOH) chemistries and gives the invention excellent ink drytime. Poor drytime is a common problem which leads to smudging and print defects, especially as ink jet printer speeds increase as technology improves. The high ink absorbency of the invention also makes this media well suited for wide format ink jet printers. The next ink receptive layer(s) are based upon pigmented, cellulose chemistry which reduces the tack of the sheet and gives the sheet good waterfastness. This is important for the end use in that the sheet may be frequently handled and exposed to dampness.

Abstract: Coating formulations, unique methods for their production and use, which have high drying capacity, maintain high levels of brightness, even after the application of a wax coating onto the printed substrate. Precipitated amorphous silicates, titanium dioxide, and other fillers are combined and coated onto heavyweight linerboard to facilitate ink drying and minimize brightness loss associated with wax dipped cartons.
