Abstract

PURPOSE: To prepare the titled adhesive having excellent stability and water resistance, by radically polymerizing a monomer mixture of a pressure-sensitive adhesive in the presence of a polymer emulsion having specific range of particle diameters, thereby forming a thick adhesive layer on the surface of the fine polymer particles.
CONSTITUTION: The objective adhesive is prepared from a polymer emulsion composition by (I) preparing fine particles having an average particle diameter of 250W850Å by the emulsion polymerization of (A) 100pts. (wt.) of a monomer having ethylenic unsaturated bond and capable of acting as a nucleus of emulsion particle (e.g. alkyl acrylate, etc.) in the presence of (B) 2W20pts. of an emulsifier (anionic surface active agent) and (C) 0.5W5pts. of a polymerization initiator (e.g. ammonium persulfate) in an aqueous medium and (II) radically polymerizing 5W50pts. (based on 1pt. of the above monomer) of a monomer mixture capable of forming a pressure-sensitive adhesive[a mixture of an alkyl acrylate, etc., a vinyl monomer having functional group, and 1W5pts. (based on 100pts. of the mixture) of a self-crosslinking monomer (copolymerizable monomer containing N-methylol group)]on the surface of the fine particle.
