Patent number: 6908671Abstract: A transparent acrylic pressure-sensitive adhesive composition which combines transparency and high-temperature adhesive properties. The transparent pressure-sensitive adhesive composition contains a polymer of one or more acrylic-based monomers and an organophilic layered clay mineral dispersed therein, wherein part of the polymer has been intercalated between layers of the clay mineral to cause interlayer separation and the clay mineral has a layer-to-layer distance of 100 ? or longer. It is produced by a process which includes: mixing 100 parts by weight of the monomers with 10 to 150 parts by weight of an organophilic layered clay mineral and 0.005 to 5 parts by weight of a polymerization initiator together with an organic solvent; exerting an external action on this mixture to thereby intercalate part of the monomers, polymerization initiator, and organic solvent into interstices of the organophilic layered clay mineral; subsequently removing the solvent; and then polymerizing the monomers.Type: GrantFiled: October 22, 2002Date of Patent: June 21, 2005Assignee: Nitto Denko CorporationInventors: Toshitsugu Hosokawa, Yoshihiro Hieda, Kazuhiko Miyauchi, Yuuichi Morimoto, Yukiko Azumi
