Title:
ULTRAVIOLET-CURABLE ADHESIVE AGENT COMPOSITION, METHOD FOR MANUFACTURING ULTRAVIOLET-CURABLE ADHESIVE SHEET, AND METHOD FOR MANUFACTURING LAMINATE
Document Type and Number:
WIPO Patent Application WO/2016/092972
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an ultraviolet-curable adhesive agent composition with which an ultraviolet-curable adhesive sheet having excellent step followability and shape retention is obtained and which is capable of imparting excellent resistance to whitening under heat and humidity to a cured product layer of the ultraviolet-curable adhesive sheet. Provided is an ultraviolet-curable adhesive agent composition which is characterised by: being obtained by reacting a polyol (a1), a polyisocyanate (a2), and a (meth)acrylic compound (a3) that has two or more hydroxyl groups; and containing a urethane resin (A) that has a hydroxyl group at a terminal thereof and further containing a polyisocyanate crosslinking agent (B), an organic solvent (C), and a photopolymerisation initiator (D). Further provided is an adhesive sheet which is characterised by being obtained by: obtaining an ultraviolet-curable adhesive sheet by drying the organic solvent (D) after coating a base material with the ultraviolet-curable adhesive agent composition; subsequently affixing an adhesive layer of the ultraviolet-curable adhesive sheet to the base material and heating; and thereafter exposing to ultraviolet radiation.
