| titleOfInvention | Polyester film |
| abstract | The subject of the present invention is that by using this polyester film which is economical, film-forming, whiteness, reflective, lightweight, and excellent in surface shape, it will not be damaged even in contact with other members, and the film Since the flaws are not obvious, it is possible to provide a surface light source with excellent brightness characteristics and excellent performance in preventing uneven brightness.nn n n The solution of the present invention is a polyester film, which is a polyester film having at least two layers of a polyester layer (A) and a polyester layer (B), wherein the polyester layer (A) forms at least one side of the polyester film A surface layer, a coating layer (C) containing particles is provided on one side of the surface layer, the particles contained in the coating layer (C) are amorphous porous particles, and the volume average particle diameter of the particles is 10 μm or more and 30 μm or less; When observing the SEM cross-section photograph of each protrusion generated when the particles were coated, the average value Dh of the distance (height of protrusion) dh from the top to the outermost surface of the polyester layer (A) was 10 μm or more and 30 μm or less. The average length Dw (width of the bottom of the protrusion) dw of the portion in contact with the polyester layer (A) is 10 μm or more and 35 μm or less; the ratio Dh / Dw of Dh / Dw is 0.70 or more and 1.00 or less; and from the polyester layer ( A) The particle length in the direction parallel to the layer A of the particles in the height of dh / 2 from the outermost layer (the width of the central portion of the protrusion) dv has an average value Dv of 10 μm or more and 35 μm or less; the ratio Dh / Dv Dh / Dv It is 0.90 or more and 1.00 or less; the ratio of Dv to Dw Dv / Dw is 0.80 or more and 1.05 or less; the particle is 1 per 1 mm 2 of the film surface More than 1,000 and less than 2000. |
