The present invention relates to a high transparent polyester film for windows, improving the particle visibility by applying an inorganic filler similar to the refractive index of a base film, and capable of securing high transmittance by lowering the surface reflectance by applying a primer having a refractive index of the coating layer lower than the refractive index of the base film. 본 발명은 기재필름의 굴절율과 유사한 무기필러를 적용하여 입자 시인성을 향상시키고, 코팅층의 굴절률을 기재필름의 굴절률보다 낮은 프라이머를 적용하여 표면 반사율을 낮춰 고투과율을 확보할 수 있는 고투명 윈도우용 폴리에스테르 필름에 관한 것이다.
