Abstract
Provided is a production method for a pressure-sensitive adhesive composition capable of sufficiently expressing each of 'attachment position correction workability' that enables a pressure-sensitive adhesive tape containing the composition to be easily aligned by the expression of good temporary attachment property, 'reworkability' that enables the tape to be easily reattached, and “temperature-sensitive strong pressure-sensitive adhesiveness” that enables the tape to express strong temperature-sensitive pressure-sensitive adhesiveness. The production method for a pressure-sensitive adhesive composition is a production method for a pressure-sensitive adhesive composition containing a cross-linked polymer in which an acrylic copolymer (A) is cross-linked by a polyurethane(meth)acrylate (B), the method including irradiating a monomer mixed liquid essentially containing a (meth)acrylate and a (meth)acrylamide with an active energy ray in the presence of the polyurethane(meth)acrylate (B).
