  • Pressure-sensitive adhesive composition
    Patent number: 7462663
    Abstract: The present invention relates to a pressure-sensitive adhesive composition, and more precisely, a pressure-sensitive adhesive composition containing an organic silane compound that exhibits excellent initial adhesive strength on a substrate, and does not leave any of the adhesive behind when removed because the adhesive power is not excessively increased even at high temperature or at high temperature and high humidity.

  • Organic silane compound
    Patent number: 7262313
    Abstract: The present invention relates to a novel organic silane compound, and more particularly, to a novel organic silane compound, useful in various applications, for the purpose of improving the affinity of an organic resin to an inorganic filler or improving the adhesion of a coating layer comprising matrix resin to a substrate. It is particularly useful for improving the adhesion of a polarizing plate adhesive for a liquid crystal display to a glass substrate, with little change over time even under hot and humid conditions.
