  • Patent number: 8617304
    Abstract: A bio-based coating for a building automatically transmits or reflects heat gain from infrared sunlight. The coating is composed of bio-based polymerized oil and a catalyst that is also a thermochromic material. The catalyst reduces the temperature for polymerization of the oil to create a suspension that forms a hardened mixture when cooled below about 100 degrees Centigrade. The thermochromic properties of the catalyst are operable to switch the hardened mixture from transparent to reflective of infrared light when the temperature rises above a switching temperature in an approximate range of 18 degrees Centigrade to 35 degrees Centigrade. The method of using the coating involves spraying a hot bio-based coating on the roof surface and allowing it to cool. The method of making involves heating the suspension to a reaction temperature, holding at the reaction temperature, and, introducing an air flow through the mixture at the reaction temperature.

  • Patent number: 4536218
    Abstract: Printed materials such as tickets, lottery forms, cards and contest forms, bearing a hidden message which is revealable by scratching off a covering opaque layer, are prepared by printing the message on the substrate, lithographing a protective layer such as a clear varnish or a pigmented varnish-ink over the hidden message, and then lithographing a hiding coat over the applied protective layer. The protective layer formulation and the hiding coat layer are both based upon compatible, preferably the same, film forming resin systems, and are deposited from a common solvent. The protective layer may provide a clear, colorless transparent film through which the message may be viewed, or a colored see-through layer, so that it constitutes one color layer also for the printing of other areas of the substrate.
