Abstract
Description
- This application claims priority of United States Provisional Patent Application 60/115,677 filed January 13, 1999 and is incorporated herein by reference.
- The present invention relates to ink jet printing media, more particularly to an aqueous coating compound for preparing an ink receiving layer on the media.
- Printers using sprayable inks, such as ink jet printers, are becoming increasingly common. These printers utilize a small aperture to selectively propel ink in response to a series of electronic commands. Ink jet printers are characterized by high speed and simple operation, making them further adaptable to the use of multiple color/multiple composition inks for computer graphics applications.
- With ever increasing demands for print quality, ink jet media, the surfaces onto which the printer applies the ink, have become ever more sophisticated in order to meet image quality requirements. Printed matter derived from an ink jet are expected to have high pixel and color densities as well as being smudge resistant and, to a large extent, archival. In order to meet these requirements, an ink jet medium should readily absorb sprayed ink so as to retain the dimensions of the original ink spot; dry with sufficient speed under normal printing conditions to allow an overlapping ink spot to be applied without bleeding or other deleterious interaction between the two spots; appear optically bright; and be resistant to curl and delamination throughout the printing process.
- Ink jet compositions are well known and are generally characterized as being aqueous with lesser amounts of hydrophilic, low vapor pressure solvents such as pyrrolidones, glycols, glycol ethers and the like. As concern about VOCs increase, the use of organic solvents in ink jet compositions is under ever increasing scrutiny. Similarly, ink jet media are increasingly expected to maintain performance requirements with aqueous inks while minimizing the use of organic solvents in the production thereof.
- Ink jet media including a support and an ink receiving top coat layer are known to the art. Top coat layers have previously included polyvinyl alcohol, polyvinyl pyrrolidone homopolymer and/or vinyl pyrrolidone copolymer, and a water soluble substance containing aldehyde groups.
