Title:
ADHESIVE COMPOSITION AND ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2017/104314
Kind Code:
A1
Abstract:
The present invention provides an adhesive composition which is characterized by containing: (A) a (meth)acrylic polymer having a hydroxyl group and/or a carboxyl group; (B) a urethane (meth)acrylate that is a reaction product of (b1) an aromatic or alicyclic polyisocyanate and (b2) a (meth)acrylic compound having a hydroxyl group and from 3 to 6 (meth)acryloyl groups; (C) a (meth)acrylic compound having 2 or more (meth)acryloyl groups; (D) a crosslinking agent; and (E) a photopolymerization initiator. The present invention addresses the problem of providing an adhesive composition that enables the achievement of an adhesive tape for temporary bonding, which has an adhesive power enough to affix an object to be bonded before ultraviolet light irradiation, while being decreased in the adhesive power to the extent that the adhesive tape is removed from the object without leaving adhesive residue by means of ultraviolet light irradiation.
