Title:
UV-CURABLE ADHESIVE COMPOSITION, ADHESIVE FILM, AND METHOD FOR MANUFACTURING ADHESIVE FILM
Document Type and Number:
WIPO Patent Application WO/2015/198775
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a UV-curable re-peelable adhesive composition whereby an adhesive tape for temporary adhesion is obtained in which adhesive force is reduced by ultraviolet irradiation sufficiently to allow peeling from an adherend without adhesive residue, despite the composition having adhesive force sufficient to enable fixing of the adherend prior to ultraviolet irradiation. The present invention provides a UV-curable re-peelable adhesive composition characterized by containing (A) a (meth)acrylic polymer having a hydroxyl group and/or a carboxyl group, (C) a (meth)acrylic compound having at least two (meth)acryloyl groups, (D) a crosslinking agent, and (E) a photopolymerization initiator. The present invention also provides an adhesive tape characterized by having a cured coating of the UV-curable re-peelable adhesive composition.
