Abstract: An improved lubricant for coating moving webs is provided. The lubricant includes a chemically modified lecithin, such as hydroxylated or acethylated lecithin, and a fatty ester to completely eliminate the need for a surfactant in the composition. The mixture avoids foaming while maintaining the coating structure, even at high speeds found in modern printing equipment and processes. The lubricant improves coating rheology and maintains coating structure. The lubricant maintains a homogeneous coating, even at high speeds, thus resulting in superior coating and paper characteristics.

Abstract: A coating composition for ink jet recording sheets, which includes a combination of hydrated amorphous synthetic silica, a synthetic binder, a cationic agent, a leveling-flow modifier, a dispersing agent, an optical brightener, and the remainder being water, is provided. The composition achieves superior brilliance, water fastness, water resistance and improved controlled absorbency of the ink with improved color density.

Abstract: A non-latex composition for saturating paper comprising a suitable hydrophobic sizing agent, ethylene acrylic acid co-polymer, and a softening agent. The ethylene acrylic acid copolymer is provided as bulk or solvent polymerized solid and rendered soluble in an aqueous alkali solution. The paper may be formulated to be repulpable. Methods for making the paper-saturating composition, methods for saturating paper, and the resulting paper are also disclosed.
