  • Patent number: 5922394
    Abstract: The present invention is directed to producing a luminescent screen used in a cathode ray tube (CRT) suitable for monochromatic or chromatic images, such as, those utilized in televisions, computers or data monitoring equipment, which require CRTs. The method of the present invention produces an ablative layer of the luminescent screen having a smooth surface with reduced surface distortions, such as, streaks and waviness, which are typically produced by conventional coating processes. When a reflective aluminum film is deposited on such a smooth ablative layer, the reflective aluminum film is also provided with a smooth surface, since it typically conforms to the underlying smooth surface of the ablative layer. As a result, CRT images having reduced distortions are produced.

  • Patent number: 5849833
    Abstract: The present invention relates to fast drying waterborne printing inks and to method of using such inks in high speed printing processes, such rotogravure and flexographic printing processes. The printing ink includes, for example, a blend of a latex binder and a polyfunctional amine. The pH of the ink is raised by adding a sufficient amount of base, to a point where essentially all of the polyfunctional amine in the blend is in a deprotonated state.
