Abstract
A pressure-sensitive adhesive prepared by emulsifying dispersing a monomer mixture containing at least 50% by weight, based on the total weight of the monomer mixture, of a long-chain alkyl (meth)acrylate with the alkyl having 9 to 13 carbon atoms in an aqueous surfactant solution to bring the monomer mixture to fine particles having an average diameter of not more than 2.0 &mgr;m and polymerizing the monomer mixture in the presence of a water-soluble polymerization initiator can provide a pressure-sensitive adhesive which possesses excellent moisture resistance, water resistance, weather resistance, and adhesion to a nonpolar adherend, such as a polyolefin plastic, and, at the same time, well-balanced tackiness properties.
