Beschreibung
Zusammenfassung:	The present invention is a polyester resin composition containing a polyester resin (A), characterized by satisfying the following conditions: (i) the acid value of the polyester resin (A) is 100 eq/ton or more; (ii) the polyester resin composition is substantially free of a curing agent; and (iii) the storage modulus E'of the polyester resin composition at 200 DEG C after the polyester resin composition is heated for 1 hour at 240 DEG C. The polyester resin composition of the present invention can inhibit harmful degassing, and is suitable for can coatings having excellent properties such as curability, retort resistance, processability, and the like. 本发明为一种含有聚酯树脂(A)的聚酯树脂组合物，其特征在于，满足以下条件：(i)聚酯树脂(A)的酸值为100eq/ton以上；(ii)聚酯树脂组合物实质上不含有固化剂；(iii)在240℃下加热处理1小时后，聚酯树脂组合物的200℃下的储能模量E'为1.0×104Pa以上。本发明的聚酯树脂组合物可以抑制有害的脱气，并且适合于固化性、耐蒸煮性、加工性等特性优异的罐用涂料。
