Removal pressure sensitive adhesive of aqueous emulsion and method for preparing the same

A method for preparing the removal adhesive comprising:

• adding 0.1 to 3 parts by weight of a polymerization initiator to 100 parts by weight of a monomer mixture (A) comprising 85 to 99.9% by weight of a (meth)acrylic acid ester monomer having an alkyl group having 1 to 14 carbon atoms i), and 0.1 to 10% by weight of a monomer having a carboxyl group or a hydroxyl group, or a mixture thereof ii);
• and
• adding 0.3 to 1.9 parts by weight of the compound having a structure of below Formula 1 (B), 15 to 25 parts by weight of a rubber based resin (C), and 1.1 to 9.9 parts by weight of a plasticizer (D) to the resulting mixture, followed by dispersion.
• wherein R1 is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms and R2 is a hydroxyl group or an alkyl group having 1 to 12 carbon atoms.
