Document Type and Number:
WIPO Patent Application WO/2016/063686
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an adhesive composition with which it is possible to obtain an adhesive sheet having excellent oleic acid resistance whereby swelling does not tend to occur and there is little change in adhesive strength even after being in contact with oleic acid for a long period of time. The present invention provides an adhesive composition that is characterized by containing a urethane resin (A), which is a reaction product of a polycarbonate polyol (a1) and a polyisocyanate (a2), a melamine crosslinking agent (B), and an organic solvent (C). This adhesive composition has extremely good coating properties, and the obtained adhesive sheet has good initial adhesive strength due to crosslinking properties, and has excellent oleic acid resistance whereby swelling does not tend to occur and there is little change in adhesive strength even after being in contact with oleic acid for a long period of time.
