PROBLEM TO BE SOLVED: To provide an aqueous hot-melt adhesive being an easily handleable aqueous-emulsion adhesive on the premise that it is excellent in bonding to polyolefin being a difficultly bondable adherend, not exhibiting tackiness when dried after being applied to a substrate to enable storage in piles, being reactivated by energy radiation or by heating, and suited for recycling because it can give a bonded object which, when becomes useless and is recycled (re-use or disposal after separation), can be easily separated into adherends with very little residual adhesive by energy irradiation. SOLUTION: The adhesive hot-melt composition is a releasable aqueous hot-melt adhesive composition prepared by formulating (A) a tackifying resin with (B) an aqueous resin emulsion and (C) a release agent.
