Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a wax for a hot-melt adhesive having excellent heat- resistance adhesive while excellently maintaining cold-proof adhesion and low melt viscosity, useful in the field of book binding, by mixing a specific hot-melt adhesive with a synthetic wax. SOLUTION: This wax is obtained by mixing a hot-melt adhesive comprising preferably 100 pts.wt. of an ethylene-based copolymer and preferably 50-100 pts.wt. of a tackifier resin such as a rosin-based resin, etc., with preferably 2-100 pts.wt. of a synthetic wax such as Fischer-Tropsch wax or the like having 80-95 deg.C melting point and the ratio of weight-average molecular weight (Mw)/ number-average molecular weight (Mn) of =1% content is 30C to 70C. |
