The present invention relates to a transfer polyester film. More particularly, the present invention relates to a transfer polyester film and a method for manufacturing the same, wherein the transfer polyester film has a coating layer with an excellent releasing property so that at the time of forming a hard coating layer in order to impart a surface gloss to an interior product, the transfer polyester film may be attached to a surface of the hard coating layer so as to allow the surface of the hard coating layer to be smoothly formed in a step of coating and curing a hard coating solution and may be removed after completely curing the hard coating layer.

Polyester film and manufacturing method thereof

Disclosed is a polyester film for optical applications, and more specifically to a polyester film having refractive index of 1.6 to 1.7 and a film having refractive index of 1.4 to 1.6 on both surfaces of the polyester film, wherein a thickness of each coating layer is 0.03 to 0.1 &#x3bc;m and total light transmittance of the entire film is 93% or more. The polyester film according to the embodiment has total light transmittance higher than the polyester film without the coating layer and is more suitable to use the polyester film for optical applications due to the excellent adhesive strength between the polyester film and layer for the post-processing working.

Polyester film for optical application

Provided is a protective film including two or more transparent plastic substrates having a functional coating layer formed thereon and laminated successively by way of an adhesive layer.

Protective film

The present invention provides a multi layered air permeation preventive layer of pneumatic tires having &#x2212;50 to &#x2212;10&#xc9; of the steep decreasing range of the elastic modulus includes inner liner layer of a non-drawn film formed from a polymer composition including 60 to 90 wt. % of a thermoplastic resin and 10 to 40 wt. % of an elastomer, and carcass layer coated on the inside and outside of the inner liner layer, the tire thus manufacture has no fracture under a severe deformation during the tire shaping process, facilitating the tire manufacture, and exhibits an air permeation preventive property as an excellent air permeation preventive layer.
