PRESSURE-SENSITIVE ADHESIVE, PRESSURE-SENSITIVE ADHESIVE MATERIAL USING SAME, AND METHOD FOR USING SAID ADHESIVE AND MATERIAL

摘要

A pressure-sensitive adhesive that satisfies at least one of the belowmentioned conditions (1 and/or 2) and contains a condensation resin that has a structural unit obtained by condensation-polymerizing polymerizable monomers including the following: a monomer (A) that has at least two carboxyl groups; and a monomer (B) that has at least two amino groups. One condition (1) is that at least one of the following is a liquid at 25°C: the first (A) of the aforementioned monomers, an anhydride thereof, and the other (B) of the aforementioned monomers. The other condition (2) is that the condensation resin contains a polyoxyalkane diyl group.
