ADHESIVE AGENT AND TEMPORARY ADHESION METHOD USING SAME

摘要

Provided is an adhesive agent which has high adhesiveness, but decomposes in the presence of an acid to realize excellent peeling performance. The adhesive comprises a polymer having units represented by the following formulas (1) and (2) as repeating units (1) (2) (where R1 is an optionally substituted alkyl group, and the like and R2 is an optionally substituted aryl group, and the like). An acid generator is added to the polymer such that the polymer will decompose when exposed to active light rays.
