摘要: Provided is a moisture-curing hot melt adhesive, which has superior overall performance, including heat resistance, adhesiveness, and solidification performance, and with which there is no reduction in the resulting IC card quality or productivity. Also provided is an IC card obtained by applying such a moisture-curing hot melt adhesive. The moisture-curing hot melt adhesive for an IC card comprises a urethane prepolymer (A) having a chemical structure (A1) derived from a polyester polyol (a1) that has isocyanate groups at the terminals and that is obtained by reacting of a diol and a dicarboxylic acid having 10 carbons or fewer. The moisture-curing hot melt adhesive has a shear modulus with non-moisture curing that is between (1×104) and (1×108) Pa at 40° C. and between (1×100) and (1×104) at 80° C. An IC card can be ideally produced by bonding a decorative material and a substrate using the moisture-curing hot melt adhesive.
