  • Publication number: 20070154656
    Abstract: The present invention to a composition for liquid crystal aligning comprising an oligoimide or oligoamic acid, which comprises a thermocurable or photocurable functional group on at least one end of the oligoimide or oligoamic acid backbone, a liquid crystal aligning layer prepared from the same, and a liquid crystal display comprising the same. The composition for liquid crystal aligning according to the present can minimize the generation of the decomposed by-products, which had been generated upon the use of polyimides, by using an oligoimide or oligoamic acid on at least one end of the backbone, instead of the conventional polyimides and has an excellent effect of improvement in alignment property, thermal stability, and image sticking.

  • Publication number: 20060035076
    Abstract: The present invention relates to an acrylic pressure sensitive adhesive composition containing organic functional groups of urethane and pyridine, more precisely an acrylic pressure sensitive adhesive composition which has excellent removability owing to its low initial peel strength on glass and excellent long-term durability since the peel strength of the pressure sensitive adhesive composition onto glass is being increased under high temperature and high humidity. The present invention also relates to an acrylic pressure sensitive adhesive composition for a polarizer having excellent adhesive functions and durability, a polarizer and a LCD containing the same.

  • Publication number: 20050277774
    Abstract: The present invention relates to a novel silane coupling agent represented by Formula 1 below and a method for manufacturing the same. Because the compound has urethane and pyridine functional groups, it has superior storage stability and good adhesion property to a matrix resin having hydroxy groups, and thus can be used in a variety of applications. where each of R1 and R2 is hydrogen or C1-C3 alkyl, a is an integer from 0 to 3, each of R3, R4, R5 and R6 is hydrogen, C1-C10 alkyl, halogen, trifluoroalkyl or alkoxyalkyl and n is an integer from 1 to 3.

  • Publication number: 20050181148
    Abstract: Provided is an acrylic pressure-sensitive adhesive composition for a polarizing film comprising an acrylic copolymer copolymerized from (meth)acrylic ester monomers having different glass transition temperatures. The acrylic pressure-sensitive adhesive composition of the present invention can minimize the problem of light leakage due to shrinkage or expansion of a polarizing film attached to a liquid crystal display panel because it has very superior stress relaxation ability while maintaining superior major properties such as adhesion durability, cuttability, etc.
