  • Patent number: 8445103
    Abstract: To provide an adhesive composition which shows high adhesion with a glass substrate and has excellent heat resistance, moisture resistance and moist heat resistance, an adhesive optical film comprising an adhesive layer made of the adhesive composition, which shows high adhesion between the adhesive layer and an optical film and effectively suppresses the occurrence of adhesive residue and lack of adhesive and also has excellent heat resistance, moisture resistance and moist heat resistance, and an image display device comprising the adhesive optical film, the adhesive optical film comprises an optical film 1, an adhesive layer 3 made of a water dispersible adhesive composition comprising, as raw monomers, an alkyl (meth)acrylate ester whose alkyl group has 4 to 18 carbon atoms, a carboxyl group-containing vinyl monomer, a phosphoric acid group-containing vinyl monomer, and a copolymerizable vinyl monomer which is optionally copolymerizable with the above monomers, wherein a carboxyl group concentration is fr

  • Patent number: 7641946
    Abstract: An adhesive film prevents static charge on peeling generated when removed from an adherend and also improves adhesion between a base material and an adhesive layer, where an under coat layer containing an organometallic is formed on the base material and then an adhesive layer is formed on the base material. Alternatively, an adhesive film showing high adhesion with a glass substrate, and including an antistatic layer, which prevents static charge on peeling generated when the surface protective film is removed, and improves adhesion between a base material and an adhesive layer, where the adhesive film includes a base material, an adhesive layer made of a water dispersible adhesive including, and an antistatic layer, containing a water soluble or water dispersible conductive material, interposed between them, and the adhesive film is stuck onto an image display device.
