Adhesive and adhesive sheet |
| abstract |
The present invention provides an adhesive that exhibits excellent initial curability, can suppress an increase in adhesive force even when exposed to a hot environment and particularly to a hot, humid environment, and can form an adhesive layer having excellent re-peeling properties. Also provided is an adhesive sheet in which said adhesive is used. The adhesive of the present invention comprises: a hydroxyl group-terminated urethane prepolymer (UPH) that is a reaction product between one or more active hydrogen group-containing compounds (H) having a plurality of active hydrogen groups per molecule, and one or more polyisocyanates (N); and a polyfunctional isocyanate compound (I). The hydrogen group-terminated urethane prepolymer (UHP) is a urethane-based adhesive having a degree of branching of 0.2-0.8 as measured by the GPC-MALS method. |
