Surface Modified Particle (e.g., Aluminum Oxide Coated Particles, Etc.) Patents (Class 428/844.2)
  • Patent number: 7854984
    Abstract: A decorative laminate having improved scratch and abrasion resistance is provided. In one embodiment, the decorate laminate includes a substrate or core, a decorative sheet on the substrate, and an overlay sheet on the decorative sheet. The overlay sheet is coated on both major surfaces to provide scratch and abrasion resistance to the laminate. The coating on the interior facing surface contains mineral particles having a particle size of from between about 10-30 microns. The coating on the exterior facing surface contains a mixture of first mineral particles having a particle size of from between about 3-8 microns and second mineral particles having a particle size of less than about 1.0 micron. The first mineral particles are preferably alumina particles, and the second mineral particles are preferably sol gel process alumina particles.
