| 20110170175 | PROCESSING FOR A WINDOW FILM HAVING QUALITY CONCERNS - In the fabrication of window films which provide solar control or other wavelength selectivity or provide safety and security, any window film which fails to satisfy required visual quality standards for its intended purpose is instead directed to a printing process which enables its use for an alternative purpose. Typically, the original purpose is one of providing uniform optical properties across the window to which the film is applied. The alternative purpose is one in which optical properties are non-uniform, since visible subject matter or patterning is printed on the window film to allow the film to be applied to windows for a decorative, privacy or informative purpose. A particularly suitable method of applying the visible subject matter or patterning is to utilize inkjet printing techniques. A particularly suitable ink is an ultraviolet-curable ink. | 07-14-2011 |
