SYNTHETIC RESIN AQUEOUS EMULSION-TYPE PRESSURE-SENSITIVE ADHESIVE AND PROCESS FOR PRODUCING IT

Japanese Patent JP3964264

B2

PROBLEM TO BE SOLVED: To provide an aqueous emulsion-type pressure-sensitive adhesive that is excellent in heat resistance, weathering resistance, strong adhesion to a polyolefin-based resin and water blushing resistance and is excellent in prevention of air pollution and protection of working environment.
SOLUTION: The process for producing the aqueous emulsion type pressure- sensitive adhesive comprises emulsifying and dispersing a component comprising (A) a monomer composed mainly of a 4-8C alkyl (meth)acrylate and (B) a tackifying resin using an aqueous solution containing (C) an anionic surfactant to form (D) a monomer-emulsified liquid having an average particle size of not more than 0.4 μm and carrying out the polymerization while dropping the monomer-emulsified liquid in (F) an aqueous solution for polymerization containing a water-soluble polymerization initiator and (E) an anionic surfactant to form a synthetic resin aqueous emulsion having the polymer particles the average particle size of which is 0.05-0.15 μm. The aqueous emulsion type pressure-sensitive adhesive uses the synthetic resin aqueous emulsion.
