PROBLEM TO BE SOLVED: To provide a hot-melt adhesive. SOLUTION: The adhesive is a moist-reactive hot-melt adhesive composition formed by admixing polyisocyanate, amorphous polyol, 1.3-6 wt.% of tri-1-6C alkyl citrate and 0.1-10 wt.% of styrene/allyl alcohol copolymer of 100-300 hydroxyl value and a number-average molecular weight (Mn) of 1,000-4,000, based on the weight of the adhesive composition wherein the group equivalent ratio of NCO/OH in the components is 1.05-2.5, these components include no crystalline polyester nor polyether and these components include water in an amount of <1 wt.% based on the total weight of the components.
