PROBLEM TO BE SOLVED: To provide a polyester resin composition having improved wet heat durability without impairing initial adhesiveness.SOLUTION: There is provided the polyester resin composition containing a polyester resin (A), a terpene-based resin (B) and a curing agent (C) and containing polyalkylene glycol having a number average molecular weight of 200 to 2000 of 1 to 30 mol% in 100 mol% of a glycol component constituting the polyester resin (A). In the polyester resin composition, the softening point of the terpene-based resin (B) is 80 to 160°C, (A)/(B)=50/50 to 95/5 (mass ratio) and the content of the curing agent (C) is 0.1 to 15 pts.mass based on total 100 pts.mass of the polyester resin (A) and the terpene-based resin (B). |
