Zusammenfassung:	PURPOSE:The titled adhesive having a suitable melting point and crystallinity at a hot-melt adhesive, comprising a copolyester containing a specific dicarboxylic acid unit, a glycol unit, and a high-molecular weight diol unit as an active ingredient. CONSTITUTION:(A) A dicarboxylic acid component consisting of 50-99mol% preferably 70-90mol% terephthalic acid and 50-1mol%, preferably 30-10mol% isophthalic acid, (B) a glycol component consisting of 99-50mol% 1,6-hexanediol and 1-50mol% 2-methyl-1,3-propanediol, and (C) one or more high-molecular weight diols of a polyalkylene ether glycol and a polycaprolactone glycol are subjected to polycondensation, to give the desired copolyester. USE:For clothing, packaging, laminating, bookbinding, etc.
