ADHESIVE COMPOSITION, ADHESIVE LAYER, ADHESIVE MEMBER AND IMAGE DISPLAY DEVICE, AND ALSO A METHOD FOR DETACHING AN OPTICAL FILM FROM AN IMAGE DISPLAY DEVICE AND DISPLAY PANEL RETRIEVAL METHOD

摘要

The pressure-sensitive adhesive composition of the invention includes a base polymer; and amphiphilic molecule particles that have an aggregate structure of amphiphilic molecules having hydrophilic group and hydrophobic group in the same molecule. The pressure-sensitive adhesive has stable adhesive characteristics and can be reduced in adhesive strength in a desired manner depending on how it is to be used.
