Title:
HEAT RELEASABLE ADHESIVE, ARTICLE AND RELEASE METHOD
Document Type and Number:
WIPO Patent Application WO/2022/230928
Kind Code:
A1
Abstract:
A heat releasable adhesive which contains a (meth)acrylic polymer having, in a side chain and/or at an end, a kinetic covalent bond that is capable of reversibly making a dissociation and a bond by means of heating and cooling. An article which comprises an adherend and the above-described heat releasable adhesive adhered to this adherend. A release method which comprises a heating step in which the above-described article is heated.
