The present invention relates to a colored polyester film for windows. The colored polyester film can block the penetration of ultraviolet light and heat rays from sunlight by attaching the film to window glass used in vehicles and buildings. The colored polyester film can also protect privacy from the outside, and also can prevent pieces of glass from scattering if the glass is broken by a sudden shock, thereby keeping safe from accidents. More specifically, the present invention relates to a polyester film including porous nanoglass which is provided at least inside the film or a coating layer on which a binder is coated along with. The polyester film of the present invention offers window glass used in the vehicles or buildings with various functions such as an insulation effects, an ultraviolet light blocking function, scattering prevention, and privacy protection. Furthermore, a porous nanomaterial has high heat insulation properties, excellent thermoreflectivity, and additional functions including a waterproof function and sound absorption, thereby supplementing shortcomings of existing insulation and thermal barrier paint. 본 발명은, 발명은 자동차, 건축물등의 창유리면에 부착시켜 태양광중 자외선 과 열선의 투과를 차단하고, 외부로부터의 프라이버시를 보호함과 동시에 갑작스런 충격에 의해 유리가 파손될 경우, 유리파편의 비산을 방지함으로서 안전사고를 유도할 수 있는 윈도우용 착색 폴리에스테르 필름에 관한 것으로서, 보다 상세히는, 다공성 나노유리가, 적어도 필름 내부 또는 바인더와 함께 코팅된 코팅층에 구비된 것을 특징으로 하는 폴리에스테르 필름이다. 본 발명은, 단열 효과, 자외선 차단, 비산 방지, 프라이버시 보호 등의 다양한 기능을 건축물 및 자동차 창유리에 부여하는 효과가 있다. 즉, 다공성 나노 소재는 높은 단열도를 지니면서 열반사율이 우수하고 방수, 흡음 등 부가기능이 있어 기존의 단열 및 차열도료의 단점을 보완하였다.
