Martin B Wolk, Thomas A Isberg, Kenneth L Hanzalik, Jeffrey C Chang, Richard E Bills, William V Dower, Terrance P Smith: Methods for preparing color filter elements using laser induced transfer of colorants with associated liquid crystal display device. Minnesota Mining and Manufacturing Company, Gary L Griswold, Walter N Kirn, Mark A Litman, May 28, 1996: US05521035 (89 worldwide citation)

Color filter elements are prepared by the laser induced thermal transfer of colorant from a color donor to a transparent, non-birefringent substrate such as glass or polymeric film. Transparent pigments which are less prone to migration, more thermally stable, and considerably more lightfast than dy ...
