Pressure sensitive adhesive composition for protective film having anti-static property and manufacturing process thereof

摘要

Provided is an adhesive composition for a protective film including an acrylic emulsion resin capable of providing contamination resistance on the film and low peel strength and minimizing generation of static electricity during peeling of the protective film. The acrylic emulsion resin includes a mixture including 80 to 99.9% by weight of a polymer of a (meth)acrylic acid ester monomer including a C1-C14 alkyl group and a (meth)acrylic acid ester monomer including an alkylene oxide unit, and 0.1 to 20% by weight of a monomer including a carboxyl group and/or a hydroxyl group or a combination thereof, and 5 to 30 parts by weight of a reactive emulsifier having a double bond structure radical-polymerizable with the polymer and including an alkylene oxide unit based on 100 parts by weight of the mixture.
