Easily dismantlable adhesive agent composition and easily dismantlable adhesive tape

摘要

Suitable adhesive properties and dismantling properties can be obtained, and an interface between an adherent/an adhesive layer or an adhesive layer/a substrate can be suitably dismantlable by the easily dismantlable adhesive composition including an acrylate polymer including a (meth)acrylate monomer having a carboxyl precursor group, 2-ethyl hexyl acrylate, and a monomer having a polar group as a monomer, and an acid catalyst or an acid generator.

主权项

1. A dismantlable adhesive composition including an acrylic polymer, and an acid catalyst or an acid generator,
wherein the acrylic polymer includes a (meth)acrylate monomer having a carboxyl precursor group, 2-ethyl hexyl acrylate, and a monomer having a polar group as a monomer, wherein the polar group is a hydroxyl group, carboxyl group, amino group, imino group or amide group, wherein the monomer constituting the acrylic polymer includes 1 to 75% by mass of the (meth)acrylate monomer having a carboxyl precursor group, 20% by mass or more of the 2-ethyl hexyl acrylate, and 1 to 30% by mass of the monomer having the polar group; and wherein the dismantlable adhesive composition is a pressure sensitive adhesive composition.
