PROBLEM TO BE SOLVED: To yield a superior adhesiveness, an anti-blocking property, and an antistatic property by blending a composition consisting of a specific copolymeric polyester resin and a specific acrylic copolymer satisfying each formula, and a substance having a sulfonate group in its molecule in an easy adhesive composition. SOLUTION: An easy adhesive white polyester film is obtained by applying coating liquid consisting mainly of an easy adhesive composition on one surface of a polyester film having a thickness of 20-500μm. Such an easy adhesive composition is of 5-80wt.% polyester resin having a second transition point of 60-200 deg.C, and an acrylic copolymer A having a glass transition temperature Tga of 50 deg.C or higher, an acrylic copolymer B having a lower glass transition temperature Tgb than that of the acrylic copolymer A, and an acrylic composition having a glass transition temperature TGc that satisfies as desired the formula III, wherein it consists of a 5-80wt.% composition of an acrylic copolymer satisfying the formulas I, II (A/B is a weight ration of the acrylic copolymers A, B), and a 5-30wt.% substance having a sulfonate group in its molecule. |
