  • Aqueous dispersion adhesive composition and adhesive film
    Patent number: 7858709
    Abstract: The aqueous dispersion adhesive composition contains an aqueous dispersion copolymer obtained by reacting of a reaction component containing alkyl (meth)acrylate whose linear or branched alkyl group has 4 to 18 carbon atoms, (meth)acrylic acid, a phosphoric acid group-containing vinyl monomer and an alkoxysilyl group-containing vinyl monomer to react; and a crosslinking agent having reactivity with a carboxyl group. In the aqueous dispersion adhesive composition, an amount of the crosslinking agent is from 0.07 to 4 parts by weight per 100 parts by weight of the aqueous dispersion copolymer, and in an adhesive layer made of the aqueous dispersion adhesive composition, an elongation at 90° C. is 200% or less.
    Type: Grant
    Filed: May 1, 2008
    Date of Patent: December 28, 2010
    Assignee: Nitto Denko Corporation
    Inventors: Toshitaka Takahasi, Kenichi Okada, Yousuke Makihata, Kuniaki Inui, Taiki Shimokuri, Mika Okada, Namiko Murayama
  • Adhesive composition, adhesive optical film and image display device
    Publication number: 20090017298
    Abstract: An adhesive composition contains a copolymer obtained by preparing a monomer component containing an alkyl(meth)acrylate whose alkyl group has 4 to 18 carbon atoms, a carboxyl group-containing vinyl monomer and a phosphoric acid group-containing vinyl monomer as essential components, and containing, as an optional component, a copolymerizable vinyl monomer which is copolymerizable with the essential components so that an amount of the alkyl(meth)acrylate is from 60 to 99 parts by weight per 100 parts by weight of the monomer component, a total amount of the carboxyl group-containing vinyl monomer, the phosphoric acid group-containing vinyl monomer and the copolymerizable vinyl monomer is from 1 to 40 parts by weight per 100 parts by weight of the monomer component and polymerizing the monomer component; and a clay mineral so that an amount of the clay mineral is from 0.5 to 10 parts by weight per 100 parts by weight of the copolymer.
