Technical Field
The present invention is directed to a coating composition for printing media. The present invention is further directed to improved printing substrates having the coating compositions thereon and methods for making the printing substrates improved. Improved printing substrates essentially increase the brilliance and brightness of the colorants applied to the coating composition, especially in comparison to colorants applied to uncoated printing media coated with conventional media.
Background of the Invention
The influence of a substrate on the brilliance and the coloring glow can be extremely important. Conventional printing substrates typically contain filler materials and / or surface coatings in order to improve the brilliance and brightness of the colorants applied thereto. Even though many attempts have been made to make an improvement to the brilliance or brilliance of the dyes, the attempts have resulted in less than acceptable color quality.
There is a need for the compositions methods, which are capable of increasing brilliance and the glare of a wide variety of dye especially of the magenta dyes. There is also a need for improved substrates, which are able to operate a superior color quality by increasing the brightness and brightness of the colors applied to them.
Synthesis of the Invention
The present invention relates to the needs described above by providing a coating composition and an improved printing substrate coated by the composition. The coating composition contains unique hollow microspheres that have a refractive index from about d 1.9 to about 2.4. The colors applied to the enhanced printing substrate exhibit exceptional brilliance and brightness compared to conventional print substrates. In addition, the present invention provides a coating that is elastic and does not cause the substrate to flow when heat is applied.
The present invention also addresses methods for making the composition and the perforated substrates described above. The superior color quality, the vibrantness of printing and the brightness of the dye are achieved by combining the above-mentioned improved substrates with any coloring composition, particularly the ink-jet inks.
These and other features and advantages of the present invention will become apparent after a review of the following detailed description of the embodiments described.
