    Patent number: 9096781
    Abstract: An aim of the prevention invention is to provide a water dispersion type acryl-based pressure-sensitive adhesive composition for re-peeling, which can prevent electrification of an adherend at the time of peeling (peeling antistatic properties) and which can form a pressure-sensitive adhesive layer excellent in adherability and re-peelable properties, and also to provide a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer formed of the pressure-sensitive adhesive composition. The re-peelable water dispersion type acryl-based pressure-sensitive adhesive composition of the present invention contains an acrylic emulsion-based polymer composed of a (meth)acrylic acid alkyl ester and a carboxyl-containing unsaturated monomer as raw material monomers, a perfluoroalkyl-containing oligomer, and an ionic compound.

  • Elastomer material containing immobilized ionic components and method for manufacturing the same
    Patent number: 9076574
    Abstract: An elastomer material containing immobilized ionic components includes an elastomer, ion-immobilized particles in which first ionic components are immobilized to metallic oxide particles, and second ionic components having electric charges opposite to electric charges of the first ionic components, wherein the ion-immobilized particles are chemically bonded to the elastomer. In the elastomer material, the first ionic components are immobilized to the elastomer through the metallic oxide particles. Therefore, the first ionic components do not easily migrate even with the passage of time or in use. Thus, the elastomer material is less susceptible to temporal changes in properties. The elastomer material is preferably used for the component of a transducer and a conductive roll.
