  • Laminate having textured wear surface and process of preparation
    Patent number: 5536530
    Abstract: A product having a textured surface thereon (and its process of manufacture) is disclosed wherein the textured surface is obtained by relieving the stress in pre-stressed polymeric chips that have been distributed as a single layer throughout a polymeric layer superimposed on a substrate.
    Type: Grant
    Filed: June 5, 1995
    Date of Patent: July 16, 1996
    Assignee: Armstrong World Industries, Inc.
    Inventors: Cheryl W. Landers, Ralph W. Wright, Jr.

  • Decorative surface covering with controlled platelet layer orientation
    Patent number: 5223322
    Abstract: A multi-dimensional image is obtained in a substantially flat surface covering by aligning the platelets of a platey material in the optical surface of the surface covering parallel to the exposed surface of the surface covering and realigning predetermined platelets to a predetermined angle with respect to the original alignment. The platelets can be realigned by pressing a gelled transparent or translucent element into the platey material containing layer or by mechanically embossing the platey material containing layer.

  • Decorative materials comprising crinkled chips
    Patent number: 4699820
    Abstract: The present invention relates to structures exhibiting unique appearances resulting from the presence of crinkled chip materials. A reflective and/or nacreous platelet or flake material is intermixed with a plasticizer and a general purpose resin, and the mixture is formed into a reflective sheet. The reflective sheet is pulverized to provide a chip material which is then used alone or in combination with other chips to form a mottle comprising a vinyl chloride resin and a plasticizer. Upon consolidating the mottle into a decorative surface, the nacreous and/or reflective chips are found to surprisingly exhibit an enhanced crinkled appearance, thereby exhibiting unique aesthetic properties.
    Type: Grant
