PURPOSE:To provide a polyester film excellent in adhesion and mechanical strength. CONSTITUTION:This film is a coated film which has been biaxially stretched and then further stretched in the lengthwise direction. The coating layer has a thickness (t) of 0.03 to 2mum and is formed from at least one polymer selected from among water-based urethanes, water-based acrylics, and water-based polyesters, the polymer containing 0.1-20wt.% particles satisfying the equation 0.5<=(d/t)<=3 (wherein (d) is the average particle diameter (mum)). |
