PRODUCTION METHOD FOR PRESSURE-SENSITIVE ADHESIVE COMPOSITION

摘要

PURPOSE: A manufacturing method of an adhesive composition is provided to provide an adhesive composition with excellent reworkability, and storing thermostatic adhesion force by crosslinking an acrylic-based copolymer by (meth)acrylate. CONSTITUTION: A manufacturing method of an adhesive composition which includes a crosslinked polymer with an acrylic copolymer crosslinked by polyurethane (meth)acrylate comprises a step of radiating active energy rays to a monomer mixture which essentially includes (meth)acrylic ester and (meth)acrylamide under the presence of urethane (meth)acrylate. The weight ratio of the acrylic copolymer and the polyurethane (meth)acrylate is 20:80-80:20.
