The coatings are non-reactive to typical indium-tin oxide touch components, metal electrodes, and black matrix inks, and can thus be used to over-coat these materials. In one aspect, the coating compositions described herein can be applied by a screen printing application process in a single layer or in multiple layers and are compatible with CNC edge grinding and acid etching. Further, the protective coatings are rigid, but not brittle, and are durable but still able to be processed rapidly. Additionally, the protective coatings are transparent, allowing alignment marks on the substrates to be visible. Finally, the protective coatings can easily be removed after substrate processing has been completed.

  • Publication number: 20120121815
    Abstract: Acrylate-containing compositions are photocured by mixing at least one N-oxyazinium salt photoinitiator, a photosensitizer for the N-oxyazinium salt, an N-oxyazinium salt efficiency amplifier, and one or more photocurable acrylates to form a photocurable composition. This photocurable composition is then irradiated to effect polymerization of the one or more acrylates. This method can be carried out in oxygen-containing environments.
