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 .mu.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.
