ABSTRACT:
A method of producing an acrylic emulsion adhesive characterized in that a composition comprising 100 parts by weight of a monomeric mixture of alkyl (meth)acrylate, acrylic acid, methacrylic acid and N-vinylpyrrolidone, 0.5-2 parts by weight of a surfactant mixture of an anionic surfactant and a nonionic surfactant, and 0.03 to 0.5 part by weight of a polymerization initiator is subjected to emulsion polymerization reaction. The acrylic emulsion adhesive of this invention is rich in solids, features good adhesion and cohesion as well as high water resistance. Therefore, by coating one side of a transparent support, this adhesive can be used as an adhesive sheet for surface protection.
