  • Patent number: 8242200
    Abstract: A process is described in which, through the combination of certain components, a thermal insulated coating paint is obtained having the properties of flexibility and lightness (low density) in a film of low thickness. This coating paint offers better thermal insulation properties with a low thickness film than other insulators having greater thickness, without requiring any additional protection. These properties are provided due to the internal structure of the coating paint wherein internal caverns are formed by the reaction of ramified chain polymers and additional materials. These characteristics are not present in traditional coating paints.

    Abstract: The present invention relates to a pressure-sensitive adhesive composition, including an interpenetrating polymer network structure in a cured state and comprising a pressure-sensitive adhesive strength stabilizer; a polarizer; and a liquid crystal display. In the present invention, by using the stabilizer having a functional group capable of rapidly reacting with a multifunctional crosslinking agent, the change of the pressure-sensitive adhesive strength over time is quickly terminated right after preparation, thereby the pressure-sensitive adhesive strength is rapidly stabilized. The pressure-sensitive adhesive of the present invention has an excellent removability in a room-temperature or warming condition. Also, the pressure-sensitive adhesive can efficiently suppress light leakage, and has an excellent workability and durability in a high-temperature and/or high-humidity condition.
