Abstract
The invention provides an improved paper coating system for ink jet printing applications. The system includes an ink jet printer containing an ink jet pen and a paper coating device for coating a print media with an effective amount of coating composition prior to printing thereon. The coating composition preferably includes from about 0.25 to about 20% by weight of a first component selected from the group consisting of polyvalent metal salt and organic acid, a second component consisting of from about 1 to about 20% by weight amine polymer, from about 0.25 to about 2.0% by weight surfactant and from about 25 to about 96% by weight glycol-based solvent having a surface tension ranging from about 25 to below about 45 dynes/cm. Since the coating composition is free from ethylene glycol-based components, the composition is safer to use and less harmful to humans and the environment. The composition has also been found to provide improved ink drying with less bleeding or smearing of image.
