  A process for producing an emulsion pressure-sensitive adhesive comprises (co)polymerizing a main monomer in the presence of a protective colloid, the protective colloid being an acrylic copolymer comprising (A-1) at least one hydrophilic monomer selected from the group consisting of acrylamide, methacrylamide, hydroxyethyl acrylate and hydroxyethyl methacrylate and (B-1) an alkyl (meth)acrylate that is copolymerizable with the hydrophilic monomer (A-1) and whose alkyl group has 4 to 18 carbon atoms, or (A-2) a hydrophilic monomer being acrylic acid and/or methacrylic acid and (B-2) an alkyl (meth)acrylate that is copolymerizable with the hydrophilic monomer (A-2) and whose alkyl group has 4 to 9 carbon atoms; the hydrophilic monomer and the alkyl (meth)acrylate being copolymerized in a weight ratio in the range of 40-70:60-30; the acrylic copolymer having a weight-average molecular weight in the range of 500 to 50000. The acrylic copolymer for forming the protective colloid may be copolymerized with a third monomer (C) being acrylonitrile and/or styrene according to need. An emulsion pressure-sensitive adhesive obtained as above exhibits particularly high adhesive property to wetting surfaces.
