PRESSURE SENSITIVE COATING FOR IMAGE FORMING |
摘要 |
Dye and developer components of a leuco dye system are separately microencapsulated. The microcapsule walls are fragile to the point of being easily ruptured. The microcapsules are mixed combined into a coating composition that is applied to a substrate and dried. Forces applied to the substrate, such as by the application of fingers or a writing instrument, rupture the capsule to produce a color change by interaction of the leuco dye system components that are released upon rupture of the capsules.
