Title:
HYDROXYL GROUP-CONTAINING COMPOUND, CURABLE RESIN COMPOSITION, CURED PRODUCT, AND LAYERED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/223923
Kind Code:
A1
Abstract:
Provided are: a compound which, while being a curable resin, can easily exhibit recoverability/re-moldability when being in the form of a cured product; a curable resin composition obtained using same; and a cured product thereof. Used in the present invention is a hydroxyl group-containing compound characterized in that: a structural unit A having one or more hydroxyl groups and a structural unit B that is different from the structural unit A are linked in the form A-B-A; and the structural unit A and the structural unit B are bonded by a reversible bond having a dissociation temperature of 120ºC or higher. This reversible bond is preferably an addition type structure formed by an anthracene type Diels-Alder reaction or a disulfide bond held between aromatic rings.
