Document Type and Number:
WIPO Patent Application WO/2015/098270
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to provide: an adhesive composition that has superior adhesive force, superior wettability to glass and plastic substrates, and low contamination of a dryer or the like; and an adhesive film obtained by applying the adhesive composition onto a substrate, and then drying/curing. The present invention provides: an adhesive composition characterized by containing a polyurethane (A) having at least two hydroxyl groups, a polyisocyanate crosslinking agent (B), at least one ester compound (C) selected from the group consisting of bis(2-ethylhexyl) adipate, diisononyl adipate, and an ester compound having an epoxy group, and an organic solvent (D); and an adhesive film obtained using the adhesive composition. The adhesive composition causes a low amount of contamination of a dryer or the like, and the obtained adhesive film has superior wettability to glass and plastic substrates. The present invention also has superior repeelability and can be especially favorably used in a surface protection film.
