Abstract:
1. A transparent pressure-sensitive adhesive composition which comprises a polymer of one or more monomers comprising from 70 to 100% by weight of at least one alkyl (meth)acrylate having 2 to 14 carbon atoms in the alkyl moiety and from 30 to 0% by weight at least one monoethylenically unsaturated monomer copolymerizable therewith and an organophilic layered clay mineral dispersed in the polymer in an amount of from 10 to 150 parts by weight per 100 parts by weight of the polymer, 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 Å or longer.
