    Abstract: The present invention relates to an acrylic pressure-sensitive adhesive composition which comprises a (meth)acrylic copolymer comprising 70 to 95 parts by weight of an alkyl(meth)acrylic acid ester monomer, in which alkyl has 2 to 14 carbon atoms, and 5 to 30 parts by weight of a (meth)acrylic acid ester monomer containing a copolymerizable aromatic group, wherein the composition has a gel fraction of 10 to 55% and a swelling ratio of 30 to 110, and a sol (uncross-linked polymer) eluted therein with a solvent has a weight average molecular weight of 600,000 or more; a polarizing plate comprising the composition; and a liquid crystal display device comprising the same. The composition according to the present invention provides workability such as an excellent durability and re-workability, and has an effect of improving a light leakage phenomenon, since the size of birefringence occurred under stress is very small.

  • Patent number: 8299156
    Abstract: A pressure-sensitive adhesive sheet has a high adhesiveness and an excellent terminal peeling resistance as well as exhibits extremely small diffusing amounts of formaldehyde and toluene. The pressure-sensitive adhesive sheet contains at least a pressure-sensitive adhesive layer of a water-dispersion type acrylic pressure-sensitive adhesive containing a water-dispersion type acrylic polymer and a tackifying resin-containing emulsion, wherein a diffusing amount of formaldehyde is less than 3 ?g/m3 and a diffusing amount of toluene is 10 ?g/g or less. As the tackifying resin-containing emulsion, a tackifying resin-containing emulsion prepared using substantially no organic solvents or a tackifying resin-containing emulsion prepared using a material other than aromatic hydrocarbon-based organic solvents can be suitably employed.

  • Publication number: 20120264861
    Abstract: The present invention relates to a process for the production of powders redispersible in water comprising an organic component and a water-soluble organic polymeric protective colloid. The organic component is dispersed and stabilized with the protective colloid in water to form a stable dispersion which is dried to form the powder redispersible in water. The organic component comprises abietic acid, sylvic acid, neoabietic acid, levopinaric acid, pimaric acid, isopimaric acid and/or palustric acid and/or their derivatives. The water-soluble organic polymeric protective colloid comprises synthetic protective colloids and naturally and/or synthetically produced biopolymer which can be synthetically modified. The obtained powder reduces efflorescence in hydraulically set systems.
